Sebaceous Carcinoma in the Right Inguinal Region with Multiple Metastases and a Poor Prognosis: A Case Report.

Introduction: Sebaceous carcinoma (SC) is a rare malignancy and can be divided into two types, ocular and extra-ocular SC. Extra-ocular SC is typically associated with a better prognosis than ocular SC. However, extra-ocular SCs located in atypical areas, such as the inguinal region, along with multiple metastases, are uncommon and present significant challenges, often leading to poorer outcomes.

Hidradenocarcinoma of the Chest With Axillary Lymph Node Metastasis: Report of 2 Cases and Systematic Literature Review of a Breast Cancer Mimicker.

Hidradenocarcinoma (HAC) is a rare malignant neoplasm originating from eccrine sweat glands, often presenting diagnostic challenges because of its resemblance to other malignancies, particularly breast cancer when occurring in the chest region. This report describes 2 cases of HAC with axillary lymph node metastasis, both initially misinterpreted clinically. The first case involved a 63-year-old woman with a sternal mass, near the right breast, initially suspected to be a sebaceous cyst.

Optimal Time for Nevus Sebaceous Excision and Predictors of Surgical Outcomes and Secondary Intralesional Neoplasms: The Mayo Clinic Experience Over 37 Years.

Background: Controversy exists around the optimal timing of resection of nevus sebaceous (NS). The authors aim to determine optimal timing of NS resection and identify predictors of surgical outcomes and secondary intralesional neoplasms.

Methods: Retrospective chart review of all patients with biopsy-proven NS diagnosis treated at the authors' institution between 1987 and 2024.

Clinical Features and Prognosis of Malignant Cutaneous Adnexal Tumors: A Retrospective Study Using a Japanese Database.

Malignant cutaneous adnexal tumors (MCATs) are rare. Previous population-based studies to determine the clinical features and prognosis of MCATs mainly included Caucasian patients, and the characteristics of Asian patients with MCATs have not yet been investigated. We aimed to investigate the characteristics of Asian patients with MCAT using a Japanese database.

Sebaceous carcinoma of the back: a case report and literature review.

Background: Extra ocular sebaceous carcinoma is a very rare, aggressive, malignant tumor arising in the adnexal epithelium of sebaceous gland that account for only about 25% of all sebaceous carcinomas (Wick et al. in Cancer 56(5):1163-72, 1985). The diagnosis of this tumor is difficult because its clinical appearance is atypical.

Comparative educational effectiveness of AI generated images and traditional lectures for diagnosing chalazion and sebaceous carcinoma.

Sebaceous carcinoma is difficult to distinguish from chalazion due to their rarity and clinicians' limited experience. This study investigated the potential of AI-generated image training to improve diagnostic skills for these eyelid tumors compared to traditional video lecture-based education. Students from Orthoptics, Optometry, and Vision Research (n = 55) were randomly assigned to either an AI-generated image training group or a traditional video lecture group.

A novel lynch syndrome kindred with hereditary adrenal cortical carcinoma.

Background: Adrenal cortical carcinoma (ACC) is an extremely rare malignancy, and advanced ACC carries a very poor prognosis. Early detection is critical since early-stage disease can be cured with surgical resection. ACC can be seen in Lynch syndrome; this case and review of the literature provide insight as to the potential biological origin of this malignancy.

Poorly differentiated sebaceous carcinoma of the lacrimal sac in a young adult: A case report.

Lacrimal sac and nasolacrimal duct tumors are extremely rare, and most of them are malignant tumors, which are often misdiagnosed as chronic dacryocystitis. We herein report a rare case of a 29-year-old female, presented with a history of watering in the right eye associated with a rapidly progressive mass for 4 months near the medial canthus. Further clinical examination revealed firm, non-tender mass occupying the lacrimal sac fossa extending above the medial canthus.

-Mutated Lynch Syndrome With 9 Synchronous Colon and Rectum Adenocarcinomas: An Extremely Rare Case Report.

Synchronous colorectal carcinoma is having more than 1 primary carcinoma detected in a single patient at the same time or within 6 months of tumor diagnosis. Metachronous colorectal carcinoma is the presence of more than 1 primary carcinoma detected consecutively in a single person after a set time interval. Patients with Lynch syndrome and Muir-Torre syndrome (a subset of Lynch syndrome) inherit a germline mutation in 1 of the mismatch repair (MMR) genes.

Intraepithelial Sebaceous Gland Carcinoma: A Multicenter Retrospective Case Series.

Purpose: Intraepithelial sebaceous gland carcinoma is a rare form of sebaceous gland carcinoma, with 10 published case reports to date. The authors report the clinical, histological, and prognostic features of this rare carcinoma.

Methods: This is a multicenter retrospective case series of patients from 3 Australian sites.
