Surgical Excision with Rotational Flap Reconstruction for Basosquamous Cell Carcinoma in Xeroderma Pigmentosa: A Case Report

Xeroderma pigmentosa (XP) is a rare autosomal recessive disorder which is characterized by a defect in nucleotide excision repair of DNA following exposure to UV radiation. This leads to hypersensitivity to sunlight causing pigmented skin lesions, photophobia and a 1000-fold increase in risk of developing cutaneous malignancies like basal cell carcinomas, squamous cell carcinomas and melanomas of head and neck. We present an interesting case of a 28 year old man with basosquamous cell carcinoma secondary to XP treated successfully with surgical excision and reconstruction with rotational flap technique.

Cutaneous Malignancy due to Arsenicosis in Bangladesh: 12-Year Study in Tertiary Level Hospital

Bangladesh is grappling with the largest mass poisoning of a population in the world due to contamination of drinking water with naturally occurring inorganic arsenic. It is estimated that 75 million people of 59 (out of 64) districts are at risk of drinking contaminated water with arsenic above 50μg/L. Long term exposure to arsenic causes cancers, including skin, lung, and bladder. This is a randomized prospective study to see the prevalence of skin cancer from arsenic affected area of Bangladesh, as well as their variation by geographical area, age, gender, location on the body, and socioeconomic conditions, in outpatient department of plastic surgery unit of Bangabandhu Sheikh Mujib Medical University (BSMMU). A total of 960 patients with skin cancers comprised of 528 males and 432 females were selected for the study from January 2004 to December 2015. In this 12-year study, we found squamous cell carcinoma, basal cell carcinoma, melanoma, and Merkel cell carcinoma to be associated with the ingestion of arsenic contaminated ground water. This is a reflection of a small part of the total national scenario of devastating result of arsenic mediated cancer in terms of skin malignancy. This study will help the future researchers who are contemplating to work on arsenic induced health problem.

Fourth Dimension in Reconstruction of Defects Following Excision of Basal Cell Carcinoma of Head and Neck!

Background:

Basal cell carcinomas (BCCs) are the most common skin tumors of the face. Excision results in soft tissue defects that require reconstruction with the focus on form, function, and patient satisfaction.

Aim:

To analyze the reconstruction of BCC excision defects of the head and neck region using local flaps and skin grafts with respect to the four dimensions of oncological reconstruction: clearance, form, function, and patient satisfaction.

Materials and Methods:

This is a prospective study conducted on 88 patients who presented with BCC of the head and neck region and who were operated in our hospital from January 2015 to December 2016 with a minimum follow-up period of 6 months up to June 2017. All patients underwent wide local excision and reconstruction using appropriate local flaps or split-thickness skin graft (SSG). Patients were analyzed with respect to age, sex, site, size, reconstruction method, complications, and patient satisfaction using the customized Patient Satisfaction Questionnaire (PSQ), derived from PSQ III.

Results:

A total of 77.3% defects were immediately reconstructed using local flaps and 18.2% underwent SSG. All flaps and grafts survived well with a complication rate of 6.8%. Approximately 72.7% of patients had good satisfaction with the medical care and reconstruction.

Conclusion:

Post-excisional defects of BCC in the head and neck region have to be reconstructed with equal weightage to the four pillars of oncological reconstruction: clearance, form, function, and patient satisfaction. Flap reconstruction is ideal as it brings about reconstruction with patient satisfaction, which is indeed the fourth dimension in any reconstructive surgery.

Trends in basal cell carcinoma incidence rates: a 16-year retrospective study of a population in central Poland

Introduction

Basal cell carcinoma (BCC) is the most commonly occurring cancer worldwide, and the overall incidence is still rising. Unfortunately, the cancer registry in Poland does not record BCC individually. Thus, the incidence of BCC in a defined population is unknown.

Aim

Analysis of incidence rates of primary BCC in central Poland during 16 years considering sex, site distribution and age to determine trends.

Material and methods

We retrospectively included all cases of BCC which were diagnosed and treated in the Department of Dermatology and Venereology, Medical University of Lodz, during the 16-year period from 1999 to 2015.

Results

We recorded 945 BCCs occurring in 890 patients (504 females - 57%, 386 males - 43%). Patient's age was between 21 and 94. A distinct increase in BCC was observed after 1999, while after 2010 during the next 2-year period a slight decrease was noted. A statistically significant correlation was observed between histopathological types of BCC and the location of the lesions. The superficial type predominates on photoprotected areas, especially on the trunk, while the nodular type occurs mainly in facial areas. No statistically significant correlation was observed between histopathological types of BCC and sex. We found a significant increase in incidence for superficial BCC among middle-age patients, while the nodular type was observed more frequently among elderly subjects.

Conclusions

Basal cell carcinoma is quite common in Poland and predominantly develops in the facial area. In middle-age patients the most common is superficial BCC, while in elderly people the nodular type is most common. Based on our results we assume that there is a strong need to educate general physicians to enable them to diagnose BCC in the early stages.

Surgical treatment of basal cell carcinoma: an algorithm based on the literature

Although basal cell carcinoma can be effectively managed through surgical excision, the most suitable surgical margins have not yet been fully determined. Furthermore, micrographic surgery is not readily available in many places around the world. A review of the literature regarding the surgical treatment of basal cell carcinoma was conducted in order to develop an algorithm for the surgical treatment of basal cell carcinoma that could help the choice of surgical technique and safety margins, considering the major factors that affect cure rates. Through this review, it was found that surgical margins of 4mm seem to be suitable for small, primary, well-defined basal cell carcinomas, although some good results can be achieved with smaller margins and the use of margin control surgical techniques. For treatment of high-risk and recurrent tumors, margins of 5-6 mm or margin control of the surgical excision is required. Previous treatment, histological subtype, site and size of the lesion should be considered in surgical planning because these factors have been proven to affect cure rates. Thus, considering these factors, the algorithm can be a useful tool, especially for places where micrographic surgery is not widely available.

Different Anatomical Distribution of Basal Cell Carcinoma Subtypes in Iranian Population: Association between Site and Subtype

Background

Basal cell carcinoma (BCC) is the most common type of human cancer. Despite the high prevalence of these tumors, there is a lack of reliable epidemiological data in some regions including Iran.

Objective

To assess the relationship between BCC subtypes and anatomical distribution in the Iranian population.

Methods

There were 876 patients with a single BCC enrolled in this study (March 2007 to March 2010; Razi Dermatology Center, Tehran, Iran).

Results

Among 876 patients, 544 were males and 332 females. Of the lesions, 43% were nodular, 32.4% mixed type, 3% superficial and rest of other subtypes. In the lesion location, 58.2% were on the face, 29.2% on scalp, 6.2% on ears, 2.3% on neck, 1.7% on trunk and 1.3% on the extremities. There was no significant difference between male and female in the BCC subtypes, but anatomical distribution of the tumor was different (p=0.002). Most of the trunk-arising BCCs were superficial, and most of the facial BCCs were nodular subtype. Also, most of the BCC subtypes occurred in patients between 40 to 80 years old and mostly on the face and scalp (p=0.04). However, superficial BCCs mostly occurred in younger patients over others (p=0.001).

Conclusion

Subtype is associated with a site, independent of gender or age. Also BCCs occurring on the trunk are mostly of the superficial subtype.

Basal cell carcinoma in Singapore: a prospective study on epidemiology and clinicopathological characteristics with a secondary comparative analysis between Singaporean Chinese and Caucasian patients

BACKGROUND/OBJECTIVES

Susceptibility to and clinical presentation of basal cell carcinoma (BCC) differ in Asian and Caucasian populations. This study aims to evaluate the epidemiological and clinicopathological characteristics of BCC in a multiracial Singaporean population, with a secondary comparative analysis between Chinese and Caucasian patients.

METHODS

We prospectively studied patients with newly diagnosed, histologically confirmed BCC at the National Skin Centre, Singapore from 2004 to 2008.

RESULTS

In total, 274 BCC from 260 patients were studied, with 19 patients having two or more tumours. Their mean age was 67.5 years and 54% were male. Chinese comprised 80% and Caucasians 14%. The Chinese were 1.8-fold as likely as Caucasians to be older than 60 years, and experienced itch thrice more frequently. Caucasians developed multiple BCC threefold and truncal or upper limb BCC 2.9-fold more frequently than the Chinese. In terms of tumour subtype, morphoeic BCC was 2.7-fold more common in Caucasians. Pigmented BCC occurred 2.7-fold more often in the Chinese, most frequently on the head and neck of elderly Chinese.

CONCLUSIONS

Compared to the Chinese, BCC occurred more often in younger Caucasians, with a predilection for the trunk and upper limb, suggesting a greater role for recreational sun exposure as a risk factor. Pigmented BCC more commonly occurred on the head and neck of elderly Chinese and may be reflective of cumulative sun exposure as a risk factor. Aggressive morphoeic BCC was more common in Caucasians than in Singaporean Chinese patients.

Basal cell carcinoma of the head and neck region: a retrospective analysis of completely excised 331 cases

The aim of the study is to analyze all completely excised BCCs in the head and neck region with regard to age, sex, personal and familial history, skin type, tumor localization and size, histopathological subtype of tumor, reconstruction method, and recurrence rates. Incompletely excised BCCs were not included in this study since incomplete excision is the most important preventable risk factor for recurrence. In 320 patients, 331 lesions were retrospectively evaluated by dividing into the following 8 subunits: scalp, frontotemporal, orbital, nose, cheek, auricula, perioral, and chin-neck area. Most of the patients were in 60-70 age group (34.7%). The nose (32.3%) was the most common site of presentation. Clinically, all lesions and, histopathologically, most of the lesions (42.2%) presented were of the nodular type. All cases of recurrence after complete excision (n = 9, 2.7%) were located in the median parts of the head and neck region and were mainly diagnosed histopathologically as sclerotic and micronodular. Even though completely excised, head and neck region BCCs, especially which are more prone to recurrence due to anatomical and histopathological properties, should be more closely monitored in order to decrease morbidity and health care costs.

Surgical excision with forehead flap as single modality treatment for Basal cell cancer of central face: single institutional experience of 50 cases

Basal cell carcinoma (BCC) is the most common skin cancer worldwide. The WHO has defined it as "a locally invasive, slowly spreading tumor which rarely metastasizes, arising in the epidermis or hair follicles and in which the peripheral cells usually simulate the basal cells of the epidermis." Here we discuss the management of BCCs of central face with surgical excision and reconstruction with forehead flap as single modality treatment. Material and Methods. This is a retrospective review of 50 patients who underwent surgical excision of BCC involving the facial region followed by primary reconstruction using forehead flaps at a single institution. There were 20 males and 30 females, mean age of 59 years. Results. No recurrence at primary site was observed during the follow-up of 1-4 yrs. There was no ectropion or exposure sequela. However, epiphora was evident. Size of lesions ranged from 2 to 6 cm. Keloid formation was seen in 2 (4%) patients. Functional and cosmetic outcomes were satisfactory. Conclusion. For the face, the best reconstructive effort eventually fails in the face of tumor recurrence. The forehead flap represents one of the best methods for repair of extensive facial defects. Complete tumor extirpation, the primary event, is the key.

Characteristics of Mixed Type Basal Cell Carcinoma in Comparison to Other BCC Subtypes

Background:

There are limited data exploring the characteristics of mixed type basal cell carcinoma (BCC).

Objectives:

To explore different characteristics of mixed type BCC.

Design:

Cross sectional study.

Materials and Methods:

825 patients with BCC enrolled in this study.

Results:

Among 825 patients, 512 (62%) were male. Three hundred and fifty five (43%) presented with nodular subtype, 267 (32.4%) with mixed subtype, 25 with superficial and the 178 remaining presented with other subtypes. Four hundred and eighty three (58.6%) of the lesions were on the face, 243 (29.5%) on scalp, 52 (6.3%) on ears, 20 (2.4%) on neck, 15 (1.8%) on trunk and 12 (1.4%) on extremities. Anatomic distribution of mixed type was as follows: 137 on face, (51.4%), 100 (37.3%) on scalp, 19 (7%) on ear, 6 (2.1%) on neck, 4 (1.5%) extremity and 1 (0.7%) on trunk, which the difference from non mixed types was statistically significant (P = 0.002). The mean diameter of the mixed types and non mixed type BCCs were significantly different (2.7 ± 2.1 cm vs. 2.2 ± 1.6 cm; P = 0.01. The prevalence of necrosis in mixed type BCC was two times higher than non mixed type BCCs (OR = 2.3, CI 95% 1.3-3.9, P = 0.001). The most frequent combined subtypes were nodular-infiltrative (P < 0.001).

Conclusion:

Mixed type BCC has differences with other BCC subtypes in anatomical distribution and tumor diameter. Indeed, mixed type BCCs are frequently composed of aggressive subtypes than nonaggressive subtypes.

Advanced Case of Invasive Basal Cell Carcinoma with Extensive Ocular Myiasis

Background

Ocular myiasis or ophthalmomyiasis means the infestation of the eye on a background of foul smelling skin infection or advanced case of skin cancers. Older people, immunocompromised patients with orbital carcinomas, diabetics and patients on immunosuppressive therapy, poor environmental sanitation and personal hygiene are prone for this infestation.

Case report

A 72-year-old female reported to us with extensive myiasis of the right eye. Lesion of 4 × 4 cm at the medial canthus and the right maxillary region with the right nasal dorsum was infested with maggots. All the larvae were removed with forceps and the wound debrided.

Intervention

The larvae were present for a week and on healing the wound was evaluated with computed tomographic (CT) scan paranasal sinuses with axial and coronal section. As no bony erosion and intracranial extension was noted hence considering the age and diabetic status surgery was not contemplated and the lesion was irradiated.

Conclusion

Ocular myiasis is a rare disease, accompanied by marked inflammatory reactions and secondary bacterial infections with massive destruction and life-threatening consequences, such as intracranial invasion. Prompt management with debridement and radical antibacterial therapy is essential.

Basal cell carcinoma of the head and neck

Basal cell carcinoma (BCC) is a malignant neoplasm derived from nonkeratinizing cells that originate from the basal layer of the epidermis and is the most frequent type of skin cancer in humans, with cumulative exposure to ultraviolet radiation as an important risk factor. BCC occurs most frequently at sun-exposed sites, with the head and neck being common areas. Tumors can be classified as nodular, superficial, morpheaform, infiltrating, metatypic, and fibroepithelioma of Pinkus. Several treatment options such as surgical excision and nonsurgical procedures are available. The choice of treatment should be determined based on the histological subtype of a lesion, cost, its size and location, patient age, medical condition of the patient, treatment availability, and the patient's wishes. The aim of any therapy selected for BCC treatment involving the head and neck is to ensure complete removal, the preservation of function, and a good cosmetic outcome.

Epidemiology of surgical treatment of nonmelanoma skin cancer of the head and neck in Greece

BACKGROUND

Nonmelanoma skin cancer (NMSC) constitutes the most common malignancy in Caucasians. Epidemiological data derive, mainly, from studies in the United States, Australia, and Northern Europe, whereas data from Mediterranean Europe are scarce.

OBJECTIVE

To provide information on the epidemiology of surgically treated NMSC of the head and neck in the region of Thrace, Northern Greece, and to evaluate the surgical treatment given.

METHODS

A retrospective review of patients surgically treated from 2004 to 2006 was conducted. Data on demographics, histology and skin cancer characteristics, and treatment efficacy and recurrence rate were extracted and analyzed.

RESULTS

One hundred seventy-nine NMSCs of the head and neck were excised and histopathologically confirmed in 160 patients, with the majority (58.7%) classified as Fitzpatrick skin type III. Histology included 125 basal cell carcinomas (BCCs) and 54 squamous cell carcinomas (SCCs). The mean age was 70.6 +/- 10.1 (range 38-97). Tumor size ranged between 2 and 50 mm. Excision with 5-mm margins was performed in every case, and the defects were closed mainly using local flaps. Incomplete excision was limited to 3.9% of cases, and the recurrence rate was 1.7%. The study revealed similar characteristics between BCC and SCC regarding age and sex but significant differences in terms of location and size.

CONCLUSIONS

Surgical resection achieves a satisfactory NMSC clearance rate in the head and neck.

Evaluation of clinical prognostic factors in T1 N0 M0 head and neck basal cell carcinoma

This retrospective study was carried out to assess the clinical outcome of stage I (ie, T1 N0 M0) head and neck basal cell carcinoma (HNBCC) and verify the impact of some clinical parameters on prognosis. The cases of 220 patients with stage I (ie, T1 N0 M0) histologically proven HNBCC were analyzed.The global disease-specific survival rate at 36 months was 100%, irrespective of the type of surgery, and thus, it was demonstrated that radical tumor resection is a viable procedure for stage I HNBCC. However, 11 (5%) of 220 cases had a recurrence. A second procedure was performed in 10 (90.9%) of 11 cases. In 3 of the 10 patients operated on twice (30%), a second recurrence was detected. Thus, a second surgical procedure on a recurring tumor is possible, but the multimodality treatment regimen should be considered for recurring tumors.
