C Bernárdez, L Requena
Malignant cutaneous adnexal neoplasms form a group of rare, typically low-grade-malignancy carcinomas with follicular, sebaceous, apocrine, or eccrine differentiation or a combination of the first 3 subtypes. Their clinical presentation is usually unremarkable, and biopsy is required to establish the differentiation subtype and the definitive diagnosis. Due to their rarity, no clear consensus has been reached on which treatment is most effective. Mohs micrographic surgery is considered to be the best option to prevent recurrence in the majority of patients...

Pilomatrixoma, also known as calcifying epithelioma of Malherbe, is a superficial benign skin tumour arising from hair follicle matrix cells (1,2) usually located in the head or neck region (1). It was first described in 1880 by Malherbe and Chenantais as a calcified epithelioma of sebaceous origin. In 1961, Forbis and Helwig proposed the term pilomatrixoma after establishing that the lesion actually originated from the outer root sheath cell of hair follicles (3-5).

Nevus sebaceus is a hamartoma of the sebaceous gland that occurs congenitally, from which various secondary tumors can arise with a prevalence of 5%-6%. Benign neoplasms commonly arise from nevus sebaceous, but they have a very low malignant potential. Two neoplasms may occasionally arise within the same lesion, but it is rare for three or more neoplasms to occur in a nevus sebaceus simultaneously. A 61-year-old male patient was admitted to our hospital for a 4 cm×2.5 cm growing tumor in a verrucous form arising within a periauricular nevus sebaceus in the post auricle of the left ear that had developed 30 years earlier...

Nevus sebaceus of Jadassohn is a congenital tumour affecting the scalp and face. It is usually presented as a pigmented patch or plaque. It is a complex cutaneous hamartoma which involves pilosebaceous follicle, epidermis and adnexal structures. Tumours that arise from nevus sebaceous are basal cell carcinoma, syringocystadenoma papilliferum, trichoblastoma and hidradenoma. The progression and frequency of the tumour increase with the age. Here we present a case of pigmented trichoblastoma over the external nose...

BACKGROUND: Reliable nuclear immunohistochemical stains for sebaceous neoplasms have not been readily available. Positive nuclear staining has been reported by GATA3 and factor XIIIa (AC-1A1). We sought to determine the diagnostic utility of these nuclear stains by comparing their staining pattern to adipophilin, a consistently positive cytoplasmic stain. METHODS: Cases with the diagnosis of sebaceous hyperplasia, sebaceous adenoma, sebaceous epithelioma/sebaceoma, and sebaceous carcinoma, nonsebaceous neoplasms (basal cell carcinoma and squamous cell carcinoma) were examined...

Muir-Torre syndrome is a rare genodermatosis inherited most frequently in an autosomal dominant fashion. Current criteria for its diagnosis include at least one sebaceous tumor and an underlying visceral malignancy. Muir-Torre syndrome is strongly associated with a germline mutation in DNA mismatch repair genes. We report two patients with a history of colorectal carcinoma who presented with sebaceous neoplasms on the face and trunk. Immunohistochemical staining of the sebaceous neoplasms demonstrated absence of mismatch repair proteins MSH2 and MSH6...

Four Felis catus papillomavirus (FcaPV) types have been fully sequenced from domestic cats. Of these, FcaPV-2 and -3 are thought to cause feline viral plaques and Bowenoid in situ carcinomas. Two short sequences of DNA from a previously unreported PV type were amplified from a feline viral plaque using consensus PCR primers. DNA was then extracted from a swab of the lesion and two sets of 'outward facing' primers were designed using the short sequences to amplify the entire 7600bp genome of the novel PV. The PV was designated FcaPV-5 and contained putative coding regions that were predicted to produce five early proteins and two late ones...

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...

PURPOSE OF REVIEW: Recent advances in the treatment of eyelid tumors have centered on the excision, evaluation of margins, role of sentinel lymph node biopsy, and adjunctive/adjuvant systemic and radiation therapy. The purpose of this review is to elaborate on these advances. RECENT FINDINGS: Mohs excision of basal cell carcinoma and squamous cell carcinoma continues to provide the greatest success in complete excision of the cancer, especially in those cases of high-risk disease including medial canthal location and recurrent disease...

A major recent advance in cancer therapy involves the use of immune checkpoint therapy for tumors with mismatch repair deficiency, as they have a high tumor mutation load and neoantigen burden. Approximately 4% of advanced colorectal cancer harbors a mismatch repair deficiency. When mismatch repair deficiency exists in the germline, there is increased susceptibility to a variety of cancers including colorectal cancer, uterine cancer, urothelial carcinoma, and skin cancer. Herein we report the case of a 62-year-old man with mismatch repair deficient metastatic colorectal adenocarcinoma, urothelial carcinoma and a history of sebaceous carcinomas...

Among the variants of squamous cell carcinoma (SCC) of the head and neck arising in mucosal surfaces, examples with sebaceous differentiation are exceedingly rare. We present a new case of SCC with sebaceous differentiation, developing in the larynx of a 64 year-old male, cigarette smoker and alcohol drinker. The tumor extended transglottically, metastasized to cervical lymph nodes, and killed the patient after 12 months. Comparing this case with four previously reported cases of SCC with sebaceous differentiation, two arising in the larynx and the other two in the adjacent pharynx, all five patients mostly shared the following features: appearance of the tumor in the seventh decade of life, heavy tobacco smoking, alcohol intake in three, surgery as mainstay treatment, tumor size between 2 and 4...

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. A diagnosis of Muir Torre syndrome should be considered in patients presenting with a sebaceous neoplasm...

AIMS: Terminal deoxynucleotidyl transferase (TdT) is a DNA polymerase expressed in immature, normal and neoplastic, lymphoid or hematopoietic cells and in neuroendocrine carcinomas, like Merkel cell carcinoma and small cell carcinoma. It has not yet been described in cells of epithelial origin. After observing TdT immunoreactivity in normal sebaceous glands we analyzed its spectrum of expression in cases of sebaceous cell hyperplasia and sebaceous cell neoplasms. METHODS & RESULTS: Twelve cases of sebaceous gland hyperplasia (SGH), and three cases of other benign lesions, namely, sebaceoma, sebaceous adenoma and sebaceous nevus, along with four archived cases of sebaceous cell carcinomas (SC) were collected and stained with TdT antibody...
