“…Immunohistochemistry of the trichilemmal carcinoma is usually negative for CEA (carcinoembryonic antigen) and EMA (epithelial membrane antigen), although late positive results have occasionally been documented. 1,11 The treatment is exclusively surgical. 1,11 Simple excision with adequate margins is safe, inexpensive and effective for the treatment of trichilemmal carcinoma.…”

Abstract:The trichilemmal carcinoma is a rare tumor that usually occurs on sun-exposed skin, especially on the face, scalp, neck and back of hands, mainly in elderly subjects but commonly between the 4th and 9th decades of life. It is not a gender-based illness. This study shows a difficult to treat case of recurrent trichilemmal carcinoma on the same location of a basal-cell carcinoma previously treated with surgery and radiotherapy. Keywords: Neoplasms, adnexal and skin appendage; Neoplasms, radiation-induced; Skin neoplasms Resumo: O carcinoma triquilemal é um tumor raro, que ocorre, geralmente, na pele exposta ao sol, principalmente face, couro cabeludo, pescoço e dorso das mãos, em indivíduos idosos, entre a 4ª e 9ª décadas de vida, sem predilação por sexo. O presente estudo mostra um caso de carcinoma triquilemal, recidivado, de difícil tratamento, em mesma topografia de um carcinoma basocelular tratado previamente com cirurgia e radioterapia.

“…Even though its histological structure suggests a certain malignancy grade, trichilemmal carcinoma has an indolent clinical course. Cases with recurrence or metastasis have been seldom reported in the literature [7][8][9] . Trichilemmal carcinomas must be distinguished from other malignant skin lesions so that the best treatment options can be adopted according to the lesion.…”

Tri chilemmal carcinoma is an uncommon low-grade malignant lesion of the outer hair sheath, originating from a hair follicle cell. The differential diagnosis includes other skin carcinomas. This study aims at reporting a case of trichilemmal carcinoma admitted at the Otorhinolaryngology and Head & Neck Surgical Ambulatory, Universidade Regional de Blumenau. The patient was an 86-year-old woman complaining of a reddish lesion on the left supraclavicular region, with one year of evolution and progressive growth, presenting a hardened vegetative mass with central ulceration, blood secretion and local pain. The tumor size was 75x45 mm, which was removed surgically with free margins. Considering that this type of lesion seldom develops metastases or local recurrences, adjuvant therapy was not adopted. The patient has been periodically followed up.Rev Bras Otorrinolaringol. V.70, n.6, 832-5, nov./dec. 2004

Malignant adnexal neoplasms

2006

Malignant cutaneous adnexal neoplasms are one of the most challenging areas of dermatopathology. Tumors of the pilosebaceous apparatus can occur as single-lineage neoplasms or may manifest as complex proliferations with multilineal differentiation patterns including not only the germinative component of the hair bulb, the inner or outer root sheath epithelium and the sebaceous gland and duct, but also the sweat duct components that relate to the apocrine secretory apparatus which empties into the follicle near the follicular bulge. Eccrine and apocrine neoplasms present a bewildering array of morphologies, which often defy precise classification. The purpose of this review is to discuss in detail the malignant neoplasms of the cutaneous adnexae and their benign and prognostically indeterminate mimics. Modern Pathology (2006) 19, S93-S126. doi:10.1038/modpathol.3800511Keywords: eccrine carcinoma; sebaceous neoplasia Malignant tumors of the pilosebaceous apparatus, their mimics and precursors IntroductionTumors of the pilosebaceous unit can occur in isolation or in combination with complex proliferations showing multilineal differentiation patterns encompassing those of sweat ducts, epidermis and stroma with its varied components. In this review, we will focus upon the malignant adnexal proliferations, considering benign entities mainly insofar as they impact the diagnostic approach to adnexal carcinoma. We will first turn to the malignant sebaceous neoplasms, their precursors and their mimics. Sebaceous adenoma Clinical FeaturesThe sebaceous adenoma is a benign neoplasm that manifests clinically as a pale yellow nodular lesion, typically of the face, that expresses itself clinically after the age of 50. Tumors range in size from o1 to 45 cm. [1][2][3][4][5][6] These lesions are associated with the Muir-Torre syndrome, comprising the coexpression of cutaneous neoplasms, including those of sebaceous type with well-differentiated squamous epithelial neoplasms, and visceral malignancies, including carcinomas of the breast, ovary, gastrointestinal tract and larynx. [7][8][9][10][11][12][13][14] An occasional patient may manifest a malignant lymphoma of nodal or extranodal type. 10,12,14 Sebaceous neoplasms in the setting of Muir-Torre syndrome are often difficult to classify, showing overlap features between all of the prototypic forms of sebaceous neoplasm ranging from hyperplasia to carcinoma. 13 HistologyThe prototypic sebaceous adenoma manifests 1-2 layers of germinitive cells which mature to form central sebocytes, and have an architecture comprising a sharply circumscribed sebaceous lobule surrounded by a compressed pseudocapsule of dermal stroma ( Figure 1a). The overlying epidermis may be attenuated, but sometimes forms a collarette around the peripheral aspect of the neoplasm. Unlike sebaceous hyperplasia, occasional mitoses may be seen in the lobules of a sebaceous adenoma and in concert with this nucleoli may be somewhat prominent, but the pleomorphism, hyperchromasia and individual cell necrosis of the se...
