BACKGROUND: Sebaceous carcinoma is an aggressive adnexal skin tumor with a predilection for the eyelids and sebaceous glands of the head and neck. CASE PRESENTATION: A 73 year-old man presented with confusion and was found to have widely disseminated sebaceous carcinoma with metastases to brain, lungs, liver, bowel, lymph nodes, and bone. Following initial treatment of the brain metastases with surgery he received post-operative radiosurgery. He then began systemic immunotherapy with pembrolizumab...

PURPOSE: To evaluate the frequency and nature of changes in T category when eyelid carcinomas are staged using the criteria in the 8th edition instead of the 7th edition of the American Joint Committee on Cancer staging manual. METHODS: Following Institutional Review Board approval, a retrospective review was conducted for all consecutive patients with the diagnosis of eyelid carcinoma treated by the senior author from January 2012 through December 2016. After a review of the clinical and pathologic data, each patient's disease was staged using both the 7th-edition and 8th-edition American Joint Committee on Cancer criteria for eyelid carcinomas...

PURPOSE: A limited number of therapies are available for patients with metastatic eyelid sebaceous carcinoma (SC). Programmed death receptor Ligand 1 (PD-L1) expression and its clinical significance in sebaceous cell carcinoma are presently unknown. This study aimed to evaluate the expression level of PD-L1 in SC. METHODS: This single centre, retrospective, and comparative study was conducted at the Ninth People's Hospital between August 1, 2013 and September 1, 2016...

Sebaceous gland carcinoma (SGC) is a rare, but life-threatening condition with a predilection for the periocular region. Eyelid SGC can be broadly categorised into two subtypes, namely either nodular or pagetoid with the latter being more aggressive and requiring radical excision to save life. We have identified key altered microRNAs (miRNA) involved in SGC shared by both subtypes, hsa-miR-34a-5p and hsa-miR-16-5p. However, their gene targets BCL2 and MYC were differentially expressed with both overexpressed in pagetoid but unchanged in nodular suggesting different modes of action of these two miRNAs on BCL/MYC expression...

Sebaceous carcinomas (SeC) are cutaneous malignancies that, in rare cases, metastasize and prove fatal. Here we report whole-exome sequencing on 32 SeC, revealing distinct mutational classes that explain both cancer ontogeny and clinical course. A UV-damage signature predominates in 10/32 samples, while nine show microsatellite instability (MSI) profiles. UV-damage SeC exhibited poorly differentiated, infiltrative histopathology compared to MSI signature SeC (p = 0.003), features previously associated with dissemination...

Bowen disease with sebaceous differentiation has been rarely documented to date. Here, we present a case of Bowen disease with sebaceous differentiation. A 67-year-old man presented with a 6.0 × 3.5 cm erythematous plaque adjacent to a 7.0 × 3.0 cm erythematous plaque on his left abdomen. Dermoscopy revealed yellow structureless areas and dotted vessels on a pink homogenous background in addition to surface scales. Histopathological examination of the upper erythematous plaque showed parakeratosis and acanthosis with proliferation of atypical keratinocytes in the epidermis...

Maria Vittoria Cicinelli, Swathi Kaliki
PURPOSE: To review and summarize the newest update on ocular sebaceous gland carcinoma (SGC) focusing on diagnosis and treatment. METHODS: A PubMed search was carried out using the terms "Sebaceous Carcinoma", "Meibomian Gland Carcinoma", "Sebaceous Cell Carcinoma", and "Sebaceous Gland Carcinoma". All studies published in English up to October 2017 were included in this review. RESULTS: Globally, the overall incidence of SGC is increasing making it the third most common eyelid malignancy after basal cell carcinoma (BCC) and squamous cell carcinoma...

Prostate adenocarcinoma is a common urologic malignant neoplasm in man. Distant cutaneous metastases (CMs) of prostate carcinoma are extremely rare with a reported incidence of 0.36% and usually they occur late. Clinically, cutaneous metastasis of prostate carcinoma can mimic other skin conditions such as cellulitis, sebaceous cyst, zosteriform lesions, telangectasias, and more, resulting in a poor recognition. Few cases of true cutaneous metastatic prostate carcinoma exist in the literature. We present a case, where the first sign of carcinoma of the prostate was CM over the anterior abdominal wall...

Purpose: To report a case of recurrent conjunctival papillary sebaceous carcinoma that was successfully treated by a combination of surgical resection, intraoperative topical mitomycin C application, and cryotherapy. Observations: A woman in her 80s developed a yellowish papillary tumor pedunculated from the surface of the upper palpebral tarsal conjunctiva in her left eye. She was histopathologically diagnosed as having sebaceous carcinoma by an excisional biopsy...

BACKGROUND: The Milan System for Reporting Salivary Gland Cytopathology is a tiered classification scheme that includes 6 diagnostic categories. Neoplasm, which is 1 of the 6 proposed categories, consists of benign neoplasm and neoplasm of uncertain malignant potential (NUMP). NUMP is reserved for a salivary gland neoplasm without clear distinction between benign and malignant. The objective of this study was to assess the risk of malignancy (ROM) of NUMP. METHODS: A retrospective analysis was conducted on 656 salivary gland fine-needle aspiration specimens from 2010 to 2016...

Ber-EP4 has been the traditional immunostain used for the detection of basaloid skin tumors. Recently, MOC-31 has shown be superior to Ber-EP4 in the detection of basosquamous basal cell carcinoma (BCC) and many centers are now using both Ber-EP4 and MOC-31 antibodies together to detect these lesions. The objective of this study was to compare the utility of using both Ber-EP4 and MOC-31 immunostains in the detection of basaloid skin tumors and to better characterize the previously unknown staining properties of MOC-31 in cutaneous lesions...

Introduction: Basaloid follicular hamartoma (BFH) is a rare, benign neoplasm of the hair follicle, characterized by multiple brown papules involving the face, scalp, and trunk. It is described by multiple clinical forms, and can present as localized or generalized. Diagnosis is made histologically via biopsy, which is important in order to distinguish BFH from basal cell carcinoma (BCC) or other malignant epithelial neoplasms. Correct diagnosis allows for the avoidance of unnecessary surgeries to remove benign lesions...

Sebaceous carcinoma of the breast (SCB) is a rare variant of ductal carcinoma arising within the mammary gland and containing at least 50% of malignant cells with sebaceous differentiation. Only 11 cases that adjust to the criteria delineated in the WHO classification have been published in the English literature, to the best of our knowledge. Here, we present the first SCB arising in the context of a deleterious BRCA2 mutation, focusing on the histopathologic and immunohistochemical features of this exceedingly rare tumor...

PURPOSE: Malignant lesions of the eyelid are the most common eye cancers. Although rarely lethal, late diagnosis can lead to serious visual morbidity. Definitive diagnosis of neoplastic lesions is pathological. Indications and types of eyelid lesions in a single high-volume ophthalmic reference center in Sao Paulo, Brazil, were analyzed. METHODS: The surgical pathological reports of patients who underwent eye removal procedures between January 2000 and December 2012 were retrieved from the electronic database of the Ophthalmology Department and retrospectively reviewed...
