Nicole M Candelario, Julio E Sánchez, Jorge L Sánchez, Rafael F Martín-García, Nicole M Rochet
Sebaceous carcinoma is an aggressive adnexal neoplasm with sebaceous differentiation. Few reports have described the histopathologic characteristics of the sebaceous carcinoma occurring extraocularly. Seventy-two cases of extraocular sebaceous carcinoma were identified from the database of a Dermatopathology Laboratory from January 1, 2007 to May 31, 2013. More cases occurred in men (60%), with a mean age at diagnosis of 65.8 years (range 39-99 years). Neoplasms were histopathologically classified as well-differentiated (22%), moderately differentiated (67%), and poorly differentiated (11%)...

Syringocystadenoma papilliferum (SCAP) is a rare, benign tumour with varied presentations that arises from the apocrine glands and at times can lead to a diagnostic dilemma. A 53-year-old male presented with a 40-year history of a scalp nodule and a recent 2-year change in its character, and a sanguinopurulent discharge. Examination revealed a 4 cm × 2 cm firm nodule upon left side of the scalp vertex, actively discharging pus and blood. No regional lymph nodes were noticeably palpable. Incision biopsy performed elsewhere showed evidence of a squamous cell carcinoma-in-situ...

BACKGROUND: Information on risk factors, epidemiology, and clinical characteristics of sebaceous carcinoma (SC) is limited. OBJECTIVE: We sought to analyze trends in SC in the United States from 2000 through 2012. METHODS: We used data from the 18 registries of the Surveillance, Epidemiology, and End Results (SEER) Program from 2000 to 2012 to calculate the cause of death, relative frequencies/incidences, 5-/10-year Kaplan-Meier survival, hazard ratios, and incidence rates for SC...

Despite recent progress in comprehensive genetic analysis, little is known about the molecular pathogenesis of sebaceous carcinoma. On the basis of the ontogenic proximity of sebaceous and mammary glands, we designed an intrinsic classification for sebaceous carcinoma adapted from that of breast cancer and evaluated its clinical significance. We investigated 42 cases of sebaceous carcinoma, including 32 ocular and 10 extraocular cases. Immunohistochemical analyses for estrogen receptor (ER), progesterone receptor (PR), androgen receptor (AR), HER2, Ki67, and CK5/6 and fluorescence in situ hybridization for the HER2 gene were performed...

PURPOSE: To identify risk factors for local recurrence and metastasis of sebaceous gland carcinoma (SGC) after wide excision with paraffin section control. DESIGN: Retrospective, observational, case-control study. METHODS: Setting: Single institution. PATIENT POPULATION: Thirty-four patients with SGC who had undergone excision with 5-mm surgical margins and paraffin section pathological analysis. Observational Procedures: The following were considered potential risk factors for local recurrence/metastasis of SGC: patient's sex, patient's age, initial diagnosis at other clinics, topical treatments at other clinics, interval between appearance of symptoms to referral to our institution, tumor location, tumor origin, tumor presentation pattern, T category, tumor size, presence/or absence of pagetoid spread, tumor differentiation, mitosis grade, growth pattern...

Management of eyelid cancers is based on surgery and/or radiotherapy (RT). The treatment objective is to control tumors with acceptable functional and esthetic outcomes. The aim of this study was to evaluate the results of radiation therapy in management of epithelial eyelid cancers, reviewing retrospectively the clinical records of patients treated in our institution from January 1989 to December 2013. We focused on clinical and histological features, treatment characteristics, tolerance and disease control...

BACKGROUND: This study was designed to evaluate the immunoexpression of DOG1, a specific marker expressed in gastrointestinal stromal tumors, in normal skin tissues and cutaneous epithelial tumors. METHODS: DOG1 immunostaining extent, intensity and pattern were evaluated in 69 cutaneous apocrine/eccrine tumors, 11 sebaceous tumors, 46 follicular tumors, 52 keratinocytic tumors and perilesional normal tissues. RESULTS: In normal tissues, DOG1 was expressed strongly in the intercellular canaliculi of eccrine glands, moderately in the myoepithelial cells of mammary and anogenital mammary-like glands, and weakly or not at all in the periphery of sebaceous lobules and the lower layer of epidermis and follicular infundibulum...

BACKGROUND: Sebaceous glands contribute significantly to the barrier functions of the skin. However, little is known about their homeostasis and tumorigenesis. Recently, increased expression of stem cell marker Lrig1 has been reported in sebaceous carcinoma-like tumors of K14ΔNLef1 transgenic mice. In this study, we analyzed the Lrig1 expression in human sebaceous tumors. METHODS: Twenty-eight formalin-fixed paraffin-embedded sebaceous tumor specimens (7 sebaceous hyperplasias, 7 sebaceous adenomas, 10 sebaceomas and 4 sebaceous carcinomas) were stained with anti-Lrig1, anti-CD44v3 and anti-Ki67 antibody...

Sebaceous gland carcinomas are skin adnexal tumours occurring in the periocular region of elderly females. It is an uncommon malignancy usually involving the upper eyelid and has an indolent course. Mainstay of treatment is surgical excision. Here we present a case of a sebaceous gland carcinoma of the lower eyelid for which wide local excision was done and the lower eyelid reconstructed using a composite flap of nasal chondromucosal graft with a nasolabial flap.

We report a patient who developed sebaceous carcinoma on the neck during therapy with immunosuppressive agents (cyclosporine, corticosteroid, methotrexate) for refractory psoriasis vulgaris, which showed rapid enlargement, leading to a fatal outcome. Multiple-organ metastases were detected. Weekly carboplatin + paclitaxel therapy resulted in the disappearance of tumor cells, but the patient died of febrile neutropenia. The development of sebaceous carcinoma is rare among psoriasis patients receiving immunosuppressive agents including cyclosporine...

A 72-year-old male visited a nearby hospital with a large tumor in his occipital region, which had existed since 20 years. Since malignant tumor was suspected, he was referred to our department. At the initial consultation, an elastic-hard, yellow-brown, sessile tumor, measuring 8 × 7 × 5 cm and with a flat surface, was observed in the occipital region. The tumor was resected and covered with artificial dermis. Histopathologically, the lesion was composed of basal-cell-like cells with nest formation in the dermis...

Two cases of primary sebaceous lymphadenoma of the thymus are presented. The patients were a man and a woman 58 and 77 years old, respectively. The female patient had a history of breast carcinoma and on follow-up was identified to have an anterior mediastinal mass; the male patient did not have any history of malignancy, and the tumor was discovered during a chest radiographic evaluation when the patient presented with symptoms of fatigue, chest pain, and dyspnea. Histologically, both lesions were characterized by the presence of solid-cystic epithelial islands in a prominent lymphocytic background...

A 78-year-old man presented with a round- to oval-shaped nodule on his right eyebrow. The lesion first developed 5 years ago as a small solitary white nodule and subsequently enlarged over the past 2 years. His medical history was unremarkable. Clinical examination revealed a 2-cm round to oval dome-shaped yellowish nodule with a dimple on the top center (Figure 1). No similar lesions were found elsewhere. With a clinical suspicion of sebaceous carcinoma, an excision of the lesion was performed under local anesthesia...

Sebaceous neoplasms encompass a range of lesions, including benign entities such as sebaceous adenoma and sebaceoma, as well as sebaceous carcinoma. The distinction of sebaceous carcinoma from benign lesions relies on histological identification of architectural or cytological features of malignancy. In this study we have assessed the diagnostic discriminatory ability of mitotic rate and immunohistochemical markers (p53, bcl-2 and p16) in a selected group of well circumscribed sebaceous neoplasms, incorporating examples of sebaceous adenoma, sebaceoma and sebaceous carcinoma...
