Lipoleiomyomas of the Uterine Cervix: A New Series including the First Recurrent Case and the First Systematic Literature Review

Primary Carcinomas of the Episiotomy Scar Site: A Systematic Literature Review

Episiotomy is a perineal incision enlarging the vaginal opening during labor, preventing severe perineal/vaginal/ano-rectal lacerations. We performed a systematic literature review (PRISMA guidelines; Pubmed, Scopus and Web of Science databases) of primary malignant tumors arising from the episiotomy site. Thirteen primary carcinomas were reported, mainly endometriosis-related histotypes (77%) (nine clear cell, CCC; one endometrioid, EC) with only two vulvar invasive squamous cell carcinomas and one adenoid cystic carcinoma of Bartholin's gland. No sarcomas, melanomas or malignant trophoblastic tumors were described. Endometriosis was associated with tumors or reported in history (62%). Malignant transformation occurred 3 to 27 (mean 16) years after diagnosis of endometriosis. Patients were usually post-/peri-menopausal (eight cases, 61%) (age range: 31-70 years, mean 50). Imaging should exclude distant (0% in our series) or lymph node metastases (three cases, 23%), looking for potential invasion of vagina (five cases, 39%), anus (including sphincter) (four cases, 31%) and/or other deep pelvic soft tissues (five cases, 39%). All patients underwent surgery, except for a CCC-patient (only chemoradiation) subsequently progressing and dying of disease. Adjuvant chemotherapy and/or radiotherapy were administered to five (39%) cases, neoadjuvant therapy to four cases (31%). Globally, three (23%) cases recurred or progressed, and two-thirds (15%) died of disease (1 CCC, 1 EC). Radical surgery with lymph node status evaluation and eventual excision should be performed when possible. Chemotherapy and/or radiotherapy can be considered in an adjuvant and/or neoadjuvant setting (or as only treatment in inoperable patients). However, the role of different treatments should be studied in further larger multicenter series.

Androgen Insensitivity Syndrome with Bilateral Gonadal Sertoli Cell Lesions, Sertoli-Leydig Cell Tumor, and Paratesticular Leiomyoma: A Case Report and First Systematic Literature Review

Androgen insensitivity syndrome (AIS) is a rare Mendelian disorder caused by mutations of the androgen receptor (AR) gene on the long arm of the X chromosome. As a result of the mutation, the receptor becomes resistant to androgens, and hence, karyotypically male patients (46,XY) carry a female phenotype. Their cryptorchid gonads are prone to the development of several types of tumors (germ cell, sex cord stromal, and others). Here, we report a 15-year-old female-looking patient with primary amenorrhea who underwent laparoscopic gonadectomy. Histologically, the patient's gonads showed Sertoli cell hamartomas (SCHs) and adenomas (SCAs) with areas of Sertoli-Leydig cell tumors (SLCTs) and a left-sided paratesticular leiomyoma. Rudimentary Fallopian tubes were also present. The patient's karyotype was 46,XY without any evidence of aberrations. Molecular genetic analysis of the left gonad revealed two likely germline mutations-a pathogenic frameshift deletion in the AR gene (c.77delT) and a likely pathogenic missense variant in the RAC1 gene (p.A94V). Strikingly, no somatic mutations, fusions, or copy number variations were found. We also performed the first systematic literature review (PRISMA guidelines; screened databases: PubMed, Scopus, Web of Science; ended on 7 December 2023) of the reported cases of patients with AIS showing benign or malignant Sertoli cell lesions/tumors in their gonads (n = 225; age: 4-84, mean 32 years), including Sertoli cell hyperplasia (1%), Sertoli cell nodules (6%), SCHs (31%), SCAs (36%), Sertoli cell tumors (SCTs) (16%), and SLCTs (4%). The few cases (n = 14, 6%; six SCAs, four SCTs, two SLCTs, and two SCHs) with available follow-up (2-49, mean 17 months) showed no evidence of disease (13/14, 93%) or died of other causes (1/14, 7%) despite the histological diagnosis. Smooth muscle lesions/proliferations were identified in 19 (8%) cases (including clearly reported rudimentary uterine remnants, 3 cases; leiomyomas, 4 cases). Rudimentary Fallopian tube(s) were described in nine (4%) cases. Conclusion: AIS may be associated with sex cord/stromal tumors and, rarely, mesenchymal tumors such as leiomyomas. True malignant sex cord tumors can arise in these patients. Larger series with longer follow-ups are needed to estimate the exact prognostic relevance of tumor histology in AIS.
