We report a case of a 68-year-old white woman presenting with 5 sebaceous neoplasms, ranging from sebaceous adenoma to sebaceoma on histopathology. Despite the lack of a personal cancer history, her multiple sebaceous neoplasms and a paternal history of colon cancer prompted testing her sebaceous adenomas for microsatellite instability (MSI) by immunohistochemistry. The results showed retained nuclear expressions of MLH1 and PMS2 while MSH2 and MSH6 proteins were absent. Read More

Sebaceous neoplasms with an organoid pattern (rippled, labyrinthine/sinusoidal, carcinoid-like, and petaloid) are rare. Previous studies suggested that the above patterns likely represent variations along a morphological continuum. The objectives of this study were to (1) validate this proposition by studying a large number of cases, (2) determine whether there are specific associations with clinical features, (3) establish their frequency, and (4) determine whether they have any association with Muir-Torre syndrome.

Hereditary nonpolyposis colorectal carcinoma (HNPCC) is an autosomal dominant genetic disorder characterized by a predisposition towards colorectal carcinoma and other extracolonic neoplasms. Histiocytic sarcoma (HS) is a very rare hematologic neoplasm characterized by a malignant proliferation of cells with histiocytic differentiation. We present the case of a 62-year-old male with previous diagnosis of MTS who presented with metastatic colorectal adenocarcinoma, bilateral papillary renal cell carcinoma, and a new squamous cell carcinoma of the scalp, treated with resection and adjuvant radiation therapy.

Background: Muir-Torre syndrome (MTS) is currently considered as a clinical variant of Lynch syndrome (LS). The clinical significance of the screening of patients with MTS-associated cutaneous tumors for the identification of LS has not yet been established. In addition, the prevalence and molecular characteristics of mismatch repair (MMR) protein deficiency in such tumors has scarcely been investigated in the Japanese population. Read More

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. Read More

Hereditary Nonpolyposis Colorectal Cancer (HNPCC), also known as Lynch Syndrome, is an autosomal dominant, tumor predisposing disorder usuallycaused by germline mutations in mismatch repair (MMR) genes. A subset of HNPCC, Muir-Torre Syndrome (MTS) also involves MMR gene defects and is generally accepted as a variant of HNPCC. MTS is typicallycharacterized by at least one visceral malignancy and one cutaneous neoplasm of sebaceous differentiation, with or without keratoacanthomas. Read More

Muir-Torre Syndrome (MTS) is a rare hereditary autosomal dominant cancer syndrome and is linked to hereditary non-polyposis colorectal carcinoma (Lynch Syndrome). Individuals develop various skin neoplasms in addition to colorectal, endometrial and upper gastrointestinal malignancies. Therapy-associated myelodysplastic syndrome (T-MDS) is an aggressive hematologic malignancy and is considered a pre-leukemic phase. Read More

Background: Muir-Torre syndrome (MTS) is a subtype of Lynch syndrome, which encompasses the combination of sebaceous skin tumours or keratoacanthomas and internal malignancy, due to mutations in DNA mismatch repair genes. Sebaceous neoplasms (SNs) may occur before other malignancies, and may lead to the diagnosis, which allows testing of other family members, cancer surveillance, risk-reducing surgery or prevention therapies.
Aim: To evaluate the efficacy of universal immunohistochemistry (IHC) screening of SNs in a service setting. Read More

Superficial epithelioma with sebaceous differentiation is the original name for a rare benign tumor that lacks consensus in the literature, both in nomenclature and in diagnostic criteria. We report the case of a 68-year-old male with a white papule on the left lower eyelid, fully excised. On histology, the lesion was a superficial, lobulated, plate-like epithelial proliferation, with small mature clusters of sebocytes and ductal structures. Read More

Muir-Torre syndrome is a clinical variant of Lynch syndrome defined by the synchronous or metachronous occurrence of at least one sebaceous neoplasm and at least one Lynch syndrome-related internal cancer. Although screening guidelines for patients with colorectal carcinomas have been established, screening guidelines for cutaneous Muir-Torre associated neoplasms are not currently available. As such, we reviewed the current evidence for the use of MLH1, MSH2, MSH6 and PMS2 immunohistochemistry when cutaneous Muir-Torre associated neoplasms are encountered. Read More

Opinion Statement: Sebaceous carcinoma is a rare and potentially aggressive cutaneous malignancy. Commonly reported in the periocular area and the head and neck region, sebaceous carcinoma can arise from any sebaceous gland in the skin. The clinical presentation may be nonspecific, and a biopsy is important to establish a diagnosis and to differentiate from mimickers including benign sebaceous neoplasms, other adnexal tumors, and basal cell carcinoma.

Sebaceous carcinoma (SC) represents a rare, aggressive eyelid malignancy with poor prognosis and is a possible component of Muir-Torre syndrome. However, genetic features as driver mutations or potential therapeutic targets are not fully elucidated. Recent a few studies have shown that SCs have concurrently multiple mutations including RAS/RAF/MAPK and PI3K/Akt pathways via next-generation sequencing in western population. Read More

Sebaceous neoplasms such as adenoma, sebaceoma, and carcinoma, although sporadic in their occurrence, are clinically significant because of their association with Muir-Torre syndrome (MTS). MTS is a rare autosomal dominant genodermatosis characterized by the occurrence of sebaceous neoplasms and/or keratoacanthomas and visceral malignancies. MTS is usually the result of germline mutations in the DNA mismatch repair genes MSH2 and, albeit less commonly, MLH1. Read More

Introduction: Lynch syndrome (LS) is a syndrome that carries a genetic predisposition to certain cancers associating, either in a single individual or in a family, a visceral tumour, mainly colorectal, with a high risk of other synchronous or metachronous cancers. LS is linked with mutations in the genes coding for proteins in the DNA repair system. Phenotypic variants of SL exist, including Muir-Torre syndrome (MTS) and Turcot syndrome (TS), both of which predispose to colorectal cancer. Read More

Background: Though a rare tumor, sebaceous carcinoma is relatively well-described in immunocompetent patients, in whom it often occurs in a periorbital distribution where it has an overall poor prognosis with a high metastasis rate. The effect of transplant-related immunosuppression on the development of sebaceous carcinoma and its outcomes has not been characterized.
Methods: We collected 9 cases from a single institution of patients developing sebaceous carcinoma after solid organ transplantation. Read More

Several autosomal dominant inherited tumour syndromes demonstrate prominent features in the oral and maxillofacial region. Although multiple organ systems are frequently involved, the target organs more frequently affected are the skin (nevoid basal cell carcinoma syndrome, Brooke-Spiegler syndrome, Birt-Hogg-Dube syndrome and Muir-Torre syndrome), gastrointestinal tract (Peutz-Jegher syndrome and Gardner syndrome) or endocrine system (multiple endocrine neoplasia type 2b and hyperparathyroidism-jaw tumour syndrome). In some syndromes, the disease is multisystem with skin index lesions presenting in the head and neck (Cowden syndrome and tuberous sclerosis complex). Read More
