Iatrogenic Breast Lymphoedema: Incidence, Diagnosis, and Associated Risk Factors

While upper limb lymphoedema following breast and axillary surgery is well established in the literature, breast lymphoedema is rarely documented. Our primary objective was to identify risk factors of breast lymphoedema, and our secondary aim was to assess the possibility of using a breast ultrasound scan to assess breast lymphoedema. This study was a case series analysis, including patients who had wide local excision for primary breast cancer treatment between January 2013 and January 2018. Patients' demographics, including age, weight, body mass index (BMI), breast volume, tumour characteristics, and histological findings, were noted. All patients had a clinical assessment and ultrasound scan 6 months and 12 months after surgery, comparing ipsilateral to the contralateral breast skin, subcutaneous thickness, as well as parenchymal changes. We have included two hundred eighty-six breast cancer; the mean age was 54.7 years SD 17.3, the mean weight was 76.5 kg SD 12.6, the mean BMI was 31.5 SD 5.2, and the mean breast volume was 1223 ml SD 179. This study identified breast lymphoedema in patients with clinically detected skin oedema in the absence of radiotherapy skin changes; skin and subcutaneous 5 mm added thickness more than the contralateral side, and based on that, 22 patients (7.7%) were found to have breast lymphoedema. We have also found that patients with high BMI, larger breast volume, upper outer quadrant tumours, and patients who had axillary lymph node clearance had an increased incidence of breast lymphoedema. The incidence of breast lymphoedema in this cohort was 7.7%. We suggest that breast lymphoedema should be considered if skin and subcutaneous thickness are 5 mm more than the contralateral side in the absence of severe radiotherapy skin changes. Also, we have found that high body mass index (BMI), larger breast volume, upper outer quadrant tumours, and patients who had axillary lymph node clearance are associated with an increased incidence of breast lymphoedema.

Safety and Efficacy of Mitoxantrone Hydrochloride Injection for Identification of Axillary Sentinel Lymph Nodes in Patients with Primary Breast Cancer

BACKGROUND

The dual technique using blue dye in combination with a radioisotope is considered the gold standard for identifying sentinel lymph nodes (SLNs) in patients with breast cancer. Unfortunately, not all cancer centres have access to radioactive material, which jeopardizes the SLN identification rate and patient safety.

AIM

We aimed to assess the safety and efficacy of mitoxantrone hydrochloride injection (MHI) for identifying axillary SLNs in patients with primary breast cancer.

PATIENTS AND METHODS

We have conducted a prospective non-randomized analysis of patients diagnosed with invasive breast cancer who agreed to participate in the study between December 2019 and December 2022. We have used the patient's medical records to collect the data. We have used the SLN intraoperative identification rate as a marker for the efficacy of the technique and both the immediate and delayed complication rates and routine blood tests as markers for the safety of the technique.

RESULTS

Out of the 296 patients, 289 (97.6%) had their SLNs identified using MHI, while seven patients (2.3%) had four-node sampling carried out because the SLNs were not identified. Liver functions were not significantly affected by MHI, and there was no technique-related readmission or reported morbidity or mortality.

CONCLUSION

We have found that the MHI technique is still inferior to the combined radioactive directed technique and patent blue V dye in SLN identification. Yet, it may serve as a safe and reliable alternative in cases where the radioactive technique is unavailable.

Clinical importance of the informed consent process in breast surgery

Breast reconstruction operations have been on the rise over the last two decades; with recent advances in medical practice, different options of breast reconstruction have been readily available. However, it is challenging for patients to grasp the knowledge and digest differences, advantages, and disadvantages of each and every procedure to be able to choose the best procedure for them. Following the Thefaut and Montgomery cases, clinicians are obliged to make sure that all the required information is presented to the patients in a structured manner and suitable environment to aid them in deciding the best procedure for them and guiding them through the informed consent process.

Evaluation of the Surgical Outcomes of Breast Oncoplastic Techniques Carried Out by a General Surgical Oncologist

Background 

With recent advances in different breast cancer treatment modalities, breast conservation surgery (BCS) has gained popularity and has become the mainstay for the treatment of early breast cancer. The model of dedicated breast surgeons working in breast units is standard in some but not all countries. We have aimed to define surgical outcomes of oncoplastic breast surgery carried out by one general surgical oncologist.

Patients and methods

We have conducted a prospective non-randomised case series analysis to assess the oncologic and aesthetic outcome of tissue displacement oncoplastic breast techniques in managing unifocal early-stage breast cancer from January 2019 to January 2020.

One surgical oncologist with 23 years of surgical oncology experience carried out all operations.

Results

We have included 50 female patients treated with variant oncoplastic volume displacement techniques. We have used the round block technique in 20%, the batwing technique in 18%, lateral mammoplasty in 20%, and medial mammoplasty in 2%. We have also carried out wise pattern therapeutic mammoplasty with inferior pedicle in 20% (10 patients), and vertical mammoplasty with superior pedicle in 20% (10 patients).

While 8% of our patients had Clavien-Dindo system grade I Immediate complications, including the surgical site infection and postoperative seroma and haematoma, 2% of patients had grade II complications in the form of partial areola and nipple complex necrosis leading to delayed wound healing requiring secondary suturing. No delayed complications or mortalities were recorded.

Eight per cent of patients required re-excision to clear margins, 74% had excellent results, 24% had good results, and 2% had fair results. In addition, 64% were very satisfied with their results, 32% were satisfied, while 4% were not satisfied with aesthetic results.

Conclusion

Based on our limited number of patients, we have found that tissue displacement oncoplastic techniques carried out by a general surgical oncologist are safe and reliable in providing satisfactory oncological outcomes with a low risk of delaying adjuvant therapy and acceptable aesthetic outcomes.

Adequate Assessment Can Affect the Management of Breast Cancer in Geriatric Population

Breast cancer (BC) risk increases with age; about a third of patients are diagnosed in age older than 65. Treatment of this age group remains controversial, leading to inferior outcomes with lower survival rates than younger patients. We aimed to evaluate performance status tools as well as the outcome of management of breast cancer in the geriatric population. We have conducted a retrospective database analysis looking into the management of breast cancer patients older than 65 years old presenting to our unit during the period between June 2015 and June 2019. All patients had triple assessment as well as multimodality performance status assessment with their treatment modalities, and outcomes are recorded and assessed. We have included 578 patients, 0.8% male and 99.2% female, and our patients' mean age was 71 years. Most of our patients scored one or two on the WHO/ECOG performance status score and Clinical Frailty Score, as well as ASA-PS score. 3.2% had no treatment, 4.3% had endocrine therapy only, 0.5% had primary endocrine therapy followed by surgery, and 92.3% underwent surgery with 4.1% complication rate. Patients who underwent breast-conserving surgery had adjuvant breast radiotherapy, and 23.7% had adjuvant chest wall radiotherapy, 78.8% had adjuvant endocrine treatment, and 4.8% had adjuvant chemotherapy out of which 30.7% had adjuvant chemotherapy and Herceptin. Objective assessment tools should be used for patients older than 65 years diagnosed with primary breast cancer to be able to scarify patients' individualised treatment options to reach the optimum outcome.

86 Adequate Assessment Can Affect the Management of Breast Cancer in The Geriatric Population

Background

Breast cancer (BC) risk increases with age; about a third of patients are diagnosed in age older than 70. Treatment of this age group remains a thorny issue leading to inferior outcome with lower survival rate compared to younger patients.

Aim

We aimed to evaluate performance status tools as well as the outcome of management of breast cancer in the geriatric population.

Method

We have conducted a retrospective database analysis looking into the management of breast cancer patients older than 65 years old presenting to our unit during the period between June 2015 to June 2019. All patients had triple assessment as well as multimodality performance status assessment with their treatment modalities and outcomes recorded and assessed.

Results

We have included 578 patients, 0.8% male and 99.2 % female, and our patients mean age was 71 years. Most of our patients scored one or two on the WHO/ ECOG performance status score, Clinical Frailty Score, as well as ASA-PS score. 3.2% had no treatment, 4.3% had endocrine therapy only, 0.5% had primary endocrine therapy followed by surgery, 92.3 % underwent surgery with 4.1% complication rate. Patients who underwent breast-conserving surgery had adjuvant breast radiotherapy, and 23.7% had adjuvant chest wall radiotherapy, 78.8% had adjuvant endocrine treatment and 4.8% had adjuvant chemotherapy out of which 30.7% had adjuvant chemotherapy and Herceptin.

Conclusions

Patients’ age should trigger the use of objective assessment tools while assessing elderly patients with a new breast cancer diagnosis, and treatment modalities offered should be individualised to reach the optimum outcome.

231 Breast Lymphedema After Breast Conservative Surgery; An Up-To-Date Systematic Review

Background

While arm lymphedema following breast cancer treatment is a common complication; breast lymphedema following treatment is not uncommon. Several risk factors were found to contribute to breast lymphedema,

Aim:

We aimed to provide a systematic review to help avoiding or management of breast lymphoedema

Method

The search term 'breast lymphedema' was combined with 'breast conservative surgery' and was used to conduct literature research in PubMed and Medline. The term lymphedema was combined with breast, conservative and surgery to search Embase database. All papers published in English were included with no exclusion date limits

Results

A total of 2155 female patients were included in this review; age ranged from 26 to 90. Mean BMI was 28.4, most of the studies included patients who underwent conservative breast surgery. Incidence of breast lymphedema ranged from 24.8% to 90.4%. Several risk factors were linked to breast lymphedema after conservative breast surgery, such as body mass index (BMI), breast size, tumour size, tumour site, type of surgery and adjuvant therapy. Treatment options focused on decongestive lymphatic therapy, including Manual lymphatic drainage (MLD), self-massaging, compression bras or Kinesio taping.

Conclusions

Breast lymphedema is a relatively common complication, yet there is no clear consensus on the definition or treatment options.

Giant Lactating Adenoma With Fibroadenomated Changes

Lactating adenomas (LAs) are uncommon benign breast tumors that typically occur in the late pregnancy or lactation period and are among the most prevalent breast lesions during puerperium. They commonly present with a painless, rapidly growing, large, mobile breast lump either late in pregnancy or the postpartum period. Despite being a condition, a core biopsy is almost always required to exclude malignancy. We are presenting a case of a 34-year-old patient who was referred to our unit with a progressive increase in size of the pre-existing right breast lump that has been there before pregnancy. Due to the massive increase in size in a short period, the lump was removed shortly after delivery with an acceptable cosmetic outcome.

P28 Breast Lymphedema after breast conservative surgery; an up-to-date systematic review

Background

While arm lymphedema following breast cancer treatment is a common complication; breast lymphedema following treatment is not uncommon. Several risk factors were found to contribute to breast lymphedema, including axillary surgery, high BMI, increased bra cup size, adjuvant chemotherapy, locoregional and radiotherapy boost and upper outer quadrant tumours.

Aim

We aimed to provide an up to date systematic review to help avoiding or managing breast lymphoedema after Breast conservative surgery for breast cancer.

Breast Cancer in the Presence of Failed Saline Breast Implants

Breast augmentation has been gaining popularity over the last two decades to correct congenital breast asymmetry or increase breast size and projection. Augmentation options started with saline implants, then silicone implants, and, recently, autologous fat transfer.

Unfortunately, breast implants are not without complications, some of which are common, like capsular contracture, implant failure and infection. Others are quite rare, such as Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL). Most of these complications will eventually require explantation in most cases, as the patients’ and implants' age and risk of complications increase.

We present a 79-year-old patient who presented to our breast unit with a left breast lump with 50-year-old saline implants. A triple assessment revealed incidental right breast cancer treated with radiofrequency identification (RFID) tag-guided wide local excision, sentinel lymph node biopsy and bilateral explantation.

Epidemiology and Predictive Factors for Persistent Breast Pain Following Breast-Conserving Surgery

Background

In general, breast pain is one of the most common causes for referral to breast units; treatment-related breast pain is frequently seen in clinical practice but not well addressed in the literature. While our primary objective was to identify the incidence of persistent breast pain following breast-conserving surgery and possible risk factors, our secondary aim was to assess the possibility of using a breast ultrasound scan to detect parenchymal changes that can contribute to breast pain.

Methods

We have conducted a prospective study including patients who had wide local excision for primary breast cancer treatment between January 2017 and January 2019. Patients’ demographics, including age, BMI, breast volume, and tumour characteristics, were noted. All patients had a clinical assessment and were asked standard questions about their breast pain each visit; they also had an ultrasound scan of the breast and axilla 6 and 12 months after surgery to look for parenchymal changes.

Results

A total of 239 female breast cancer patients were included in our analysis. The mean age was 43.9 years, mean weight was 72.8 kg, mean BMI was 27.4 and mean breast volume was 1173 ml. In total, 38.5% had standard wide local excision, and 61.5% had oncoplastic resection; the mean specimen weight was 74.6 grams. All patients had adjuvant whole breast radiotherapy. We found that patients with younger age, larger breast size, high BMI, oncoplastic resections, and persistent parenchymal changes are associated with an increased incidence of postoperative breast pain while the type of axillary procedure and adjuvant chemotherapy had no significant effect.

Conclusion

Persistent postoperative breast pain was noted in 33% of our patients. We have also indicated that younger patients, patients with larger breast, those with high BMI, with preoperative breast pain, who had oncoplastic resections, and patients with persistent parenchymal changes, as fat necrosis and scarring, are associated more with persistent breast pain.

Failure of an Ancient Breast Implant Can Lead to Significant Morbidity

Implant-based breast reconstruction is the most popular reconstruction option following mastectomy. However, it is not without complications, some of which can be trivial while others can lead to significant morbidity, especially in geriatric patients. Severe capsular contracture, implant failure, infection, or suspected breast implant-associated anaplastic large cell lymphoma are examples of complications that will eventually require explantation in most cases. As patients with implant-based reconstruction age, the risk of complications increases, which should be considered by treating physicians. We describe the case of a 90-year-old patient who presented to our emergency department after a fall with worsening confusion, which was attributed to a 60-year-old left breast implant rupture and a peri-implant infected hematoma confirmed with CT and ultrasound.

Mondor's Disease of the Arm Following Breast Cancer Treatment

Mondor's disease is a rare, peculiar form of superficial thrombophlebitis which mainly affects the subcutaneous veins of the breast, anterior chest wall, neck, axilla, upper limbs and penis.

In most cases, it presents with rapid development of a painful subcutaneous cord-like structure that later becomes less painful, but a fibrous band persists. Unfortunately, aetiology and management are not very clear, but it is a self-limiting condition in most cases.

We are presenting a rare case of a patient who developed Mondor's disease in the antecubital fossa of the right arm following chemotherapy for breast cancer.

Routine cavity shaves following breast conserving surgery; friend or foe?

BACKGROUND

Radial margin status is considered one of the most important prognostic predictor for patients undergoing breast-conserving surgery (BCT), not only related to regional recurrence but also to 5y survival, especially in patients with invasive disease.

AIM

While our primary aim was to evaluate whether doing routine radial cavity shaves following at the time of primary conservative breast surgery will decrease the need for a second operation or not, our secondary aim was to assess time added to the operation to resect and mark the radial shaves, as well as patients' satisfaction with the results.

MATERIAL AND METHODS

We have conducted a case series prospective analysis, including158 patients who underwent breast-conserving surgery looking into the histological status of resection margins and radial shaves, added time taken to take and mark the shaves as well as patients' satisfaction.

RESULTS

158 female breast cancer patients have been included in our analysis, the mean age was 56 years; total number of lesions was 160. While 89.3% of lesions were palpable, 10.6% were not requiring wire-guided localisation. Mean tumour size was 24 mm SD 7, final histology revealed that 86.8% lesion was invasive ductal carcinoma, 5.6% invasive lobular carcinoma, 1.2% medullary carcinoma. 12.4% had invasive disease as well as DCIS, and 1.8% had DCIS only with no invasive disease. Mean preoperative breast volume was 723 ml, Mean wide local excision specimen weight was 73 g, and mean shave weight was 1.6 g. Total number of radial margins was 640, 81.8% was clear, 14.6% was close, and 3.4% was involved. Total number of shaves was 640 out of which 98.7% was clear 0.7% was close and 0.4% was involved. Out of the 160 lesions, 3.7% required a second procedure to clear margins, out of which 2.5% had re-excision for close or involved single shaves each while 1.2% had mastectomy due to close or involved two shaves each. Average time utilised in resection of radial shaves and marking was 7 min 0.6% of patients developed a haematoma, 1.8% had a Seroma, and 1.2% had wound infection. Mean hospital stay was 1day SD 1.

CONCLUSION

Routine radial cavity shaves not only ensure microscopic clearance, reduce the need for re-excision with no significant added operating time but also has no impact on patients' satisfaction.

Vacuum-Assisted Breast Biopsy System: No Innovation Without Evaluation

Background Vacuum-assisted breast biopsy (VABB) has recently been gaining more popularity as a modality to reach the final diagnosis, especially in indeterminate breast lesions, resulting in a decreased number of surgical interventions and unnecessary follow-ups. Objective While our primary aim was to look into the outcomes of the VABB technique, our secondary aim was to assess the impact of the method on changes in patients' management. Patients and methods This study was a retrospective database analysis of vacuum-assisted biopsies (VABs) carried out at our breast unit during the period between January 2011 and January 2018. All our cases were image-guided; the caliber of vacuum-assisted needles used was 8 gauge (G) and 11 G. Patient demographics, lesion characteristics, and outcomes were retrieved from patients' notes and the hospital database. Results A total of 122 female patients were included in the analysis, out of whom 41.8% (51 patients) were screen-detected, and 58.1% (71 patients) were symptomatic presentations. The mean lesion size on imaging was 14.8 mm (SD: 12.6); 50% (61 patients) had stereotactic vacuum-assisted breast biopsy (SVAB), and 50% (61 patients) had ultrasound-guided vacuum-assisted breast biopsy (US-VAB). Post-procedure histology was upgraded in 19.6% (24 patients), downgraded in 18.8% (23 patients), and remained unchanged in 61.4% (75 patients). Conclusion VABB is a safe and efficient procedure for the diagnosis and management of indeterminate and suspicious breast lesions. It provides an adequate amount of tissue, which can help in upgrading or downgrading histopathologically diagnosed patients, thereby decreasing the need for surgery.

Phyllodes Tumours Will Only Get Bigger During Pandemic Restrictions

Phyllodes tumours of the breast are rare fibroepithelial stromal tumours which are morphologically very different from epithelial breast cancer. Its diagnosis and management has always been challenging till the World Health Organization (WHO) divided it into two-three subtypes in 2003, only then it was found that incidence and management and follow-up of these three subtypes need to be completely different to reach the optimum outcome.

We are presenting a case of a 47-year-old female who presented relatively late (due to pandemic restrictions) with a large phyllodes tumour requiring mastectomy as well as adjuvant treatment.

The Appendix Is Not Always Alone in Amyand's Hernia

An inguinal hernia is one of the most common surgical conditions accounting for both elective as well as acute admissions. Amyand's hernia is a rare entity of inguinal hernia, which represents a very small percentage of all inguinal hernias. While in most cases it is an incidental finding encountered during routine repair of an inguinal hernia, in other cases, it might be the reason for acute presentation. We are presenting a case of a six-week-old male who was found intraoperatively to have not only the appendix but also the caecum in the hernia sac. We believe that a preoperative groin ultrasound scan would aid clinical diagnosis and facilitate surgical planning in these cases.

Small Bowel Perforation as a Consequence of Strangulated Direct Inguinal Hernia

Inguinal hernia is probably one of the most common surgical conditions, with strangulation accounting for a good number of acute surgical admissions. It has always been known that direct hernias are less likely to strangulate due to wide hernial defects in comparison to indirect hernia. For that reason, some surgeons do not attempt repair of direct hernias in elderly patients. We present a relatively uncommon case of a 58-year-old gentleman who presented with clinical signs of an incarcerated inguinal hernia; which was found at exploration to be a strangulated direct hernia with small bowel perforation. We believe that direct inguinal hernia should always be included in the differential diagnosis of incarcerated or strangulated groin hernia.

Football Size Jejunal Gastrointestinal Stromal Tumour

Gastrointestinal stromal tumours (GISTs) are considered the most common mesenchymal neoplasms of the alimentary tract, yet they account for only 0.2% of all gastrointestinal neoplasms.

We are presenting a case of a 68-year-old gentleman who was diagnosed with a 250 mm jejunal GIST only when he presented with abdominal pain and fullness in the upper abdomen. We believe that detailed medical history, followed by prompt investigations, will help in early diagnosis of small GISTs with less malignant potential, which in turn will lead to better outcomes.

Breast Lymphedema After Conservative Breast Surgery: An Up-to-date Systematic Review

Although arm lymphedema following breast cancer treatment is a common complication; breast lymphedema following treatment is not uncommon. Several risk factors were found to contribute to breast lymphedema, including axillary surgery, high body mass index (BMI), increased bra cup size, adjuvant chemotherapy, locoregional and radiotherapy boost, and upper outer quadrant tumors. We aimed to provide a review to help avoiding or management of breast lymphedema. The search term 'breast lymphedema' was combined with 'breast conservative surgery' and was used to conduct a literature research in PubMed and Medline. The term lymphedema was combined with breast, conservative, and surgery to search the Embase database. All papers published in English were included with no exclusion date limits. A total of 2155 female patients were included in this review; age ranged from 26 to 90 years. The mean BMI was 28.4 of the studies that included patients who underwent conservative breast surgery. Incidence of breast lymphedema ranged from 24.8% to 90.4%. Several risk factors were linked to breast lymphedema after conservative breast surgery, such as BMI, breast size, tumor size, tumor site, type of surgery, and adjuvant therapy. Treatment options focused on decongestive lymphatic therapy, including manual lymphatic drainage, self-massaging, compression bras, or Kinesio taping. Breast lymphedema is a relatively common complication, yet there is no clear consensus on the definition or treatment options.

Methylene Blue Spray for Identification of Parathyroid Glands During Thyroidectomy

Background: Hypocalcaemia is a common delayed complication after thyroidectomy. Several studies have identified risk factors and possible ways to prevent post-thyroidectomy hypocalcemia. The purpose of our study is to evaluate the effectiveness of an intraoperative methylene blue spray to identify parathyroid glands during thyroidectomy.

Materials and methods: We have conducted a prospective non-randomised cohort study with 50 patients who underwent hemithyroidectomy or total thyroidectomy between January 2019 and January 2020. During thyroidectomy, 1 ml (10 mg) of 1% methylene blue was sprayed over the parathyroid glands, the inferior thyroid artery, and the recurrent laryngeal nerve.

Results: Our study included 50 patients with ages ranging from 18 to 80 years old (43.0±9.7). We were able to identify the parathyroid glands with the intraoperative methylene blue spray in 82% of cases, with no significant postoperative complications.

Conclusion: Our study concludes that the methylene blue spray is a safe, feasible, and effective technique to identify parathyroid glands.

A Prospective Observational Study Assessing the Relationship Between Solitary Thyroid Nodule Size and Incidence of Malignancy

Background

Solitary thyroid nodule (STN) is a well-documented entity. Autopsy data indicate a 50% prevalence of thyroid nodules >10 mm in patients without clinical evidence of thyroid disease. Prevalence of palpable nodules is 4-7%. Solitary thyroid nodules are often asymptomatic and found incidentally. Fine needle aspiration cytology is recommended to determine the nature of the thyroid nodule. 5-10% of the thyroid nodules are found to be malignant following thyroidectomy.

Objective

Our study aims to explore the relationship between solitary thyroid nodule size and malignancy.

Methods

A prospective, observational analysis looking at preoperative thyroid ultrasound scan findings and post-operative histology for a total of 100 female patients referred to our unit within a university hospital from November 2016 to April 2019. Statistical analysis including One-Way ANOVA was performed where appropriate.

Results

Total number of patients was 100 female patients divided according to the size of the nodule into three groups with the correlation between the size of the nodule and the incidence of malignancy.

Group A: Patients with a STN <20 mm; eight patients; post-operative histology = all benign.

Group B: Patients with a STN measuring 20-40 mm; 80 patients: 68 patients were benign, and 12 patients (12%) were malignant (incidence of malignancy in the group is 15%).

Group C: Patients with a STN >40 mm; 12 patients: eight patients were benign, four patients were malignant, (incidence of malignancy = 33%).

Correlation between the size of the nodule and the incidence of malignancy:

Group A: 0/8 malignancy; Group B: 12/80 patients were malignant; Group C: 4/12 malignant.

Conclusion

Our results suggest that the size of a solitary thyroid nodule cannot be reliably used for at predicting malignancy and should not be influencing patient’s management.

Subungual Squamous Cell Carcinoma in a Patient with Psoriasis

Subungual squamous cell carcinoma (SCC) is a rare malignant tumour with an indolent course and unknown aetiology. It is usually misdiagnosed as a benign lesion, resulting in delayed treatment. Although psoriasis is not a precancerous skin condition, the treatment modalities cyclosporine and psoralen with ultraviolet A (PUVA) might increase the risk of developing cutaneous SCC, although a relationship has not been confirmed. We describe a patient with psoriasis who had been treated with cyclosporine and PUVA 6 years previously. He developed back SCC 2 years later, a subungual skin lesion after another 2 years and presented to us 1 year later, when nail elevation and biopsy revealed SCC.

LEARNING POINTS

Subungual squamous cell carcinoma (SCC) is often misdiagnosed as a benign condition so most cases are invasive by the time of diagnosis; nail elevation and biopsy are recommended in all suspicious cases.Although psoriasis is not an independent risk factor for subungual SCC, the cyclosporine and PUVA used to treat psoriasis are risk factors for cutaneous SCC.The aetiology for subungual SCC is still unclear, but it should be suspected in patients with psoriasis and a suspicious presentation.

Shingles (Herpes Zoster) Mimicking Acute Abdomen

Shingles is a very well-known viral infection caused by the varicella-zoster virus leading to painful skin rash. Although shingles can occur anywhere, it most often appears as a single stripe of blisters around the hypochondriac region. We are presenting a rare atypical presentation of shingles, as our patient presented with a picture of the acute abdomen a couple of days prior to the eruption of skin lesions.

A systematic review of symptomatic small bowel lipomas of the jejunum and ileum

Introduction

Small bowel lipomas are rarely encountered benign adipose growths found within the small intestine wall or mesentery. Limited up-to-date evidence exists regarding such lipomas. We aim to aid clinical decision-making and improve patient outcomes through this comprehensive review.

Methodology

The terms 'small bowel,' 'small intestine,' 'jejunum' and 'ileum' were combined with 'lipoma.' EMBASE, Medline and PubMed database searches were performed. All papers published in English from 01/01/2000-31/12/2019 were included. Simple statistical analysis (t-test, Anova) was performed.

Results

142 papers yielded 147 cases (adults = 138, pediatric = 9). Male = 88, female = 59 (average age = 49.9 years). Presenting symptoms: abdominal pain = 68.7%; nausea/vomiting = 35.3%, hematochezia/GI bleeding = 33.3%; anaemia = 10.9%; abdominal distension = 12.2%; constipation = 8.9%; weight loss = 7.5%. Mean preceding symptom length = 58.1 days (symptoms >1 year excluded (n = 9)). Diagnostic imaging utilised: abdominal X-Ray = 33.3%; endoscopy = 46.3%; CT = 78.2%; ultrasound = 23.8%. 124/137 (90.5%) required definitive surgical management (laparotomy = 89, laparoscopcic = 35). 9 patients were successfully managed endoscopically. Lipoma location: ileum = 59.9%, jejunum = 32%, mesentery = 4.8%. Maximal recorded lipoma size ranged 1.2-22 cm.Mean maximum lipoma diameter and management strategy comparison: laparotomy 5.6 cm, laparoscopic = 4.4 cm, endoscopic = 3.7 cm, conservative = 4.5 cm. One-way Anova test, p value = 0.21. Average length of stay (LOS) was 7.4 days (range = 2-30). T-test p value = 0.13 when comparing management modalities and LOS. 4 complications, 0 mortality.

Conclusions

Important previously undocumented points are illustrated; a clearer symptom profile, diagnostic investigations utilised, size and site of lipomas, types and effectiveness of management modalities, associated morbidity and mortality. Open surgery remains the primary management. No statistically significant difference in LOS and lipoma size is demonstrated between management strategies. Endoscopic and laparoscopic techniques may reduce utilising invasive surgery in the future as skillset and availability improve.

Characteristics of Chest CT Images in Patients With COVID-19 Pneumonia in London, UK

Background and objective Novel coronavirus 2019 (COVID-19) outbreak was first reported in Wuhan, Hubei Province in China in December 2019; it has then spread quickly and exponentially beyond the Chinese borders and is now regarded as a global pandemic. We aimed to evaluate the chest CT radiological characteristics and lesion distribution patterns in patients of COVID-19 pneumonia in London, UK. Methods We performed a retrospective study and reviewed data of patients with clinically suspected COVID-19 who underwent chest CT between February 1 and May 5, 2020. All patients underwent the reverse transcription-polymerase chain reaction (RT-PCR) test. Lung lesion characteristics and distribution patterns were evaluated by two radiologists. Fisher's exact test was used for statistical analysis, and a p-value of <0.05 was considered statistically significant. Results A total of 18 patients (nine men and nine women) were analyzed. All of them had bilateral patchy lesions in the chest CT images. There was no correlation between the severity score and mortality (p=0.790). The distinctive CT features included ground-glass opacity (GGO) and consolidative patchy amorphous lesions, bilateral posterior and peripheral multi-lobar lung involvement, pleural effusions, subpleural fibrotic lines, subpleural sparing, vascular engorgement, occasional crazy paving, occasional mediastinal lymphadenopathy, pleural thickening, lack of cavitation, and absence of reverse halo (atoll) signs. Conclusion CT can facilitate the diagnosis of COVID-19 pneumonia. Our UK cohort showed slight variations compared with previously reported Asian and continental European cases with respect to chest CT images.

Positive Chest CT Features in Patients With COVID-19 Pneumonia and Negative Real-Time Polymerase Chain Reaction Test

Objectives Clinically suspicious novel coronavirus (COVID-19) lung pneumonia can be observed typically on computed tomography (CT) chest scans even in patients with a negative real-time polymerase chain reaction (RT-PCR) test. The purpose of the study was to describe the CT imaging findings of five patients with negative RT-PCR results on initial and repeated testing but a high radiological suspicion of COVID-19 pneumonia. Methods Out of 19 clinically and/or radiologically diagnosed COVID-19 patients from our institution, five patients were selected for our study who had typical findings of COVID-19 on CT scan despite two negative RT-PCR results. Two district general hospital radiologists reviewed the chest CT images without prior knowledge of the RT-PCR test results. Scans were analyzed for the density of opacification and the distribution of disease. Results Out of 19 patients, five (26%) had initial negative RT-PCR test findings but positive CT chest features consistent with COVID-19. All patients had typical CT imaging findings of COVID-19. These included one patient with purely ground-glass opacities (GGO) and four patients with mixed GGO and consolidation. The typical distribution of parenchymal involvement was bilateral, posterior, and peripheral. Of the five patients with negative RT-PCR and positive CT findings, the range of CT severity score was 5 to 14. The median score, seen in three patients, was a score of 5, which corresponded to mild disease. One patient had a score of 8, corresponding to moderate disease, and one patient had severe disease with a score of 14. Conclusion Lung parenchymal changes related to COVID-19 can be seen on chest CT clearly despite repeated RT-PCR negative results.

A challenging case of a chyle leak following axillary lymph node clearance

Chyle leak following axillary lymph node clearance is a rarely reported complication. We present a case of chylous leakage following axillary lymph node clearance, which was diagnosed on clinical grounds. Surgical re-exploration was undertaken due to ongoing high output. However, the chylous leak recurred post-operatively, if at a lower rate. The patient was subsequently managed successfully with conservative measures, primarily utilizing regular aspiration and compression bandaging to the axilla.

Giant Lactating Adenoma - Size of a Shot Put Ball

Lactating adenomas are benign breast tumours which normally present in the peripartum period. Aetiology, pathogenesis, best diagnostic modality and management are not yet clear in the literature. We present a case of a 32-year-old pregnant patient who was re-referred to us with a progressively increasing left breast lesion, pre-existing prior to pregnancy, which was found to be a huge lactating adenoma.

Penile Rings: No Innovation without Evaluation

Penile strangulation is a rare clinical entity which if left untreated can cause serious urogenital problems. We present the case of 45-year-old male patient who presented with penile strangulation after applying a metallic ring. Strangulation of the external male genitalia is a serious problem that requires urgent intervention in order to avoid serious complications. If left untreated, it can result in gangrene and penile amputation. Management of penile strangulation is a real challenge for the treating surgeon and should be treated as an emergency in order to avoid vascular compromise.

LEARNING POINTS

Penile strangulation by metallic rings is not routinely encountered in daily emergency practice and can be a challenge for the treating surgeon.Problem awareness is a crucial part of the management of such a rare entity.Every attempt should be made as early as possible to preserve penile arterial supply.

Knotted nasogastric tube: a rare, overlooked yet preventable complication

Nasogastric tubes (NGTs) have long been used for various indications, most commonly to decompress the stomach of its contents in intestinal obstruction or after abdominal surgery, to provide enteral feeding or to allow enteral liquid medication administration. Recently greater importance has been given to the correct placement NGTs to avoid serious complications. We present a case of a spontaneously knotted NGT that was identified and safely removed without complications, but which may have resulted from suboptimal placement. We discuss this case to raise awareness of this complication and how to minimize the likelihood of it happening and improve patient outcome.

A case of successful conservative management of gallstone ileus

Gallstone ileus is an uncommon complication of cholelithiasis but an established cause of mechanical bowel obstruction in the elderly. Perforation of the small intestine proximal to the obstructing gallstone is rare, only a handful of cases having been reported. Management is mainly surgical, but conservative treatment is occasionally appropriate. We report the case of an 86-year-old female who presented with a clinical picture of bowel obstruction, proven to be related to gallstone ileus which resolved spontaneously. We discuss the role of conservative management for this condition.

Massive angiomyofibroblastoma of the glans penis

Male genital tract angiomyofibroblastoma (AMF) is a rare benign tumour, with a total of 34 cases reported in literature. We are presenting a case of AMF of the glans penis in a 68-year-old man who presented with a progressively increasing in size large lesion located on the tip of his penis. Following routine investigations, the lesion was surgically excised with no adjuvant treatment, the patient was followed-up for 5 years with no evidence of local, nodal or distant recurrence. As AMF of the glans penis is extremely rare, there is not enough literature to support management guide lines, but it appears that AMF responds very well to complete surgical excision; occasional cases of recurrence have been previously reported, so a long-term follow-up is advised.

Umbilical Sebaceous Cyst Mimicking Infected Urachal Sinus

In addition to the most likely diagnoses for umbilical signs in adults (umbilical hernia, metastatic tumour, endometriosis, congenital abnormalities such as umbilical-urachal sinus and gallstones retained or spilled at the umbilicus), the differential diagnosis should also include epidermoid cyst arising from the skin of the umbilicus. We describe the case of a young man who presented with a persistent umbilical discharge which was initially thought to be umbilical-urachal sinus, but later found to be a sebaceous cyst.

Intrahepatic Gallbladder

Gallbladders have been reported in various ectopic locations. An intrahepatic gallbladder is one where the gallbladder lies within the liver parenchyma or has a subcapsular location along the anterior inferior right lobe of the liver. Intrahepatic gallbladders can have impaired function leading to the formation of gallbladder stones. We present the case of a 57-year-old man who was found to have an intrahepatic gallbladder which was not detected before a retrograde open cholecystectomy was carried out without intra-operative or postoperative complications. Awareness of ectopic gallbladders and their recognition allows proper intra-operative planning.

Bilateral persistent sciatic arteries complicated by unilateral acute lower limb ischaemia

We present a case of a middle-aged Caucasian woman who developed acuteon top of chronic limb ischaemia secondary to thrombotic occlusion of a persistent sciatic artery (PSA). Timely investigation and treatment were instituted resulting in a favourable outcome. PSA is an uncommon congenital, developmental, arterial anomaly which can cause serious lower limb complications such as acute or critical limb ischaemia and amputation. As this condition is rarely encountered in regular clinical practice, and has a limb-threatening potential, it is important to be aware of its cause, presentation and management. We describe the embryologic aetiology of PSA and discuss different investigation modalities and treatment options.

Calcified gallbladder cancer: is it preventable?

A case of a newly diagnosed calcified gallbladder cancer is presented, who had pre-existing porcelain gallbladder. Due to the advanced stage of the disease at presentation, the patient had a poor outcome. The investigation and management of gallbladder carcinoma is discussed as well as the relationship with porcelain gallbladder. We conclude that there is only a weak association between porcelain gallbladder and gallbladder cancer, but because gallbladder cancer typically presents late, a stratified approach to offering cholecystectomy to asymptomatic porcelain gallbladder is reasonable.
