11/91. Postauricular sebaceous carcinoma arising in association with nevus sebaceus.

    BACKGROUND: Sebaceous carcinoma is an uncommon malignant neoplasm usually associated with the ocular adnexa. Despite the widespread anatomic distribution of sebaceous glands, extraocular sebaceous carcinoma occurs with far less frequency. methods: A 27-year-old man was examined with the presenting complaint of a slowly enlarging subcutaneous mass. It was associated with an overlying, irregular, verrucoid epidermal plaque. RESULTS: Histologic and electron microscopic examination of the mass revealed a malignant sebaceous neoplasm occurring in conjunction with an overlying nevus sebaceus. The dermal neoplasm contained numerous cytoplasmic and stromal hyaline globules. CONCLUSIONS: We report a case of extraocular sebaceous carcinoma arising in the postauricular region in association with a nevus sebaceus and exhibiting the unusual histologic feature of hyaline globules.

12/91. A sebaceous tumor in a patient with acquired immunodeficiency syndrome.

    The prevalence of cutaneous malignancies is higher in immunosuppressed patients. Here, we describe a case with a rapid growing and unusually large sebaceous tumor in a patient with acquired immunodeficiency syndrome. Sebaceous adenomas are commonly rare, benign tumors of sebaceous glands. An association of AIDS and a solitary, large sebaceous adenoma has not been described yet. This emphasizes the role of an intact immune system in the suppression of benign and malignant tumors. tubular adenoma; tumor; AIDS

13/91. Sebaceous carcinoma of the lung: histologic and immunohistochemical characterization of an unusual pulmonary neoplasm: report of a case and review of the literature.

    Sebaceous neoplasms, including carcinomas, are tumors most often seen around the eye and eyelid. Cases of extraorbital sebaceous tumors associated with skin adnexa are less common. The parotid gland may also be a source for sebaceous neoplasms, and cases associated with minor salivary gland tissue have also been reported. Once beyond the oropharynx, individual cases of pharyngeal and laryngeal sebaceous tumors are reported. The case of a patient with primary sebaceous carcinoma of the bronchus is presented. Our case is that of an endobronchial mass that has histopathologic features of a sebaceous carcinoma, with predominance of areas with morphologically classic sebaceous differentiation, confirmed by oil red O stain for lipid, analyzed by immunohistochemistry and evaluated ultrastructurally. This unique tumor extends the spectrum of extraocular, extracutaneous neoplasms with sebaceous differentiation from existing single reports in the hypopharyx and larynx to now include bronchus.

14/91. Sebaceous lymphadenoma of the lip: report of a case of minor salivary gland origin.

    A case of sebaceous lymphadenoma occurring in the lip of a 73-year-old female is described. The patient had noticed a painless mass in the region of her upper lip for a year. The surgically removed tumor, measuring about 10 mm in diameter, was located just beneath the lip mucosa, expanding into the submucosal and muscle layer. Histologically, the tumor was well encapsulated and consisted of scattered round-shaped islands of small squamous epithelial cells with focal but apparent sebaceous differentiation in a background of lymphoid stroma. This is the first case report of sebaceous lymphadenoma of minor salivary gland origin.

15/91. Sebaceous carcinoma arising from nevus sebaceus: a case report.

    BACKGROUND: Sebaceous carcinoma (SC) is a rare, aggressive, malignant tumor that is derived from adnexal epithelium of sebaceous glands that are distributed mostly in the skin of the head, neck, and hair-bearing regions of the body. OBJECTIVE: To discuss the clinical and histologic features and the prognosis of the extraocular SC. METHOD: We report a case of SCs of the scalp arising from a previous lesion clinically compatible with a nevus sebaceous. The lesion was surgically excised completely. RESULTS: The postoperative course was free of complications, and the patient was clinically free of disease at her recent follow-up 2 years after treatment. CONCLUSIONS: The absence of metastasis or cutaneous recurrence in our patient, notwithstanding the size of the lesion and its late removal, almost 25 years after the first signs of its growth, confirms a much improved prognostic behavior for extraocular SCs.

16/91. Sebaceous lymphadenocarcinoma of salivary glands.

    Primary sebaceous neoplasms of the salivary glands are extremely rare occurrences; furthermore, sebaceous lymphadenocarcinoma has only been reported in three patients. We report a case of sebaceous lymphadenocarcinoma arising in a lymphadenoma of the parotid gland. The patient was a 55-year-old man who presented with a parotid mass of 3 years' duration. Histologically, the lesion consisted of a sebaceous lymphadenoma with transition to a sebaceous carcinoma. The cytologic touch-preparation at the time of frozen section showed clusters of benign sebaceous cells in a rich lymphocytic background together with tridimensional clusters of malignant epithelial cells, strongly raising the suspicion of a malignant neoplasm arising in a benign sebaceous lesion. Malignant transformation of the sebaceous lymphadenoma, although rare, should be considered in enlarging, locally invasive parotid lesions, considering that clinical behavior and prognosis will be determined by the nature of the malignant component.

17/91. Sebaceous gland adenoma of the tarsal conjunctiva in a patient with muir-torre syndrome.

    PURPOSE: To highlight the recognition and diagnosis of muir-torre syndrome (MTS) in patients with sebaceous tumors of the eyelid/conjunctiva and to determine the role of immunohistochemical markers as a screening test in patients with muir-torre syndrome. DESIGN: Single interventional case report. methods: The clinical and family history was reviewed from the records of a 41-year-old man who had a sebaceous gland adenoma of the tarsal conjunctiva of the left upper eyelid. The lesion was completely excised and submitted for histopathologic examination. Immunohistochemical stains using an antibody to MSH2 were performed on the paraffin-embedded sections of the tumor. RESULTS: Histopathologic examination of the tumor showed a lobular pattern with basaloid cells at the periphery of the lobules with central areas of sebaceous differentiation. Immunohistochemical stains showed a lack of MSH2 expression in the tumor, which is highly consistent with MTS. CONCLUSIONS: muir-torre syndrome should be considered in patients initially seen with sebaceous tumors of the eyelid. immunohistochemistry for MSH2 is a practical initial approach to screen for MTS in patients with sebaceous tumors.

18/91. Sebaceous carcinoma of the head and neck. Case report and literature review.

    Sebaceous carcinoma is uncommon, with fewer than 400 cases reported. Usually, lesions arise in the meibomian glands of the eyelid; however, extraocular lesions within the head and neck have been reported. Regardless of the location, sebaceous malignancies must be considered aggressive neoplasms with a potential for regional and distant metastasis. diagnosis may be difficult, given the low incidence and inconsistencies in histopathologic classification. Recently, needle aspiration cytologic characteristics have been delineated, with this procedure becoming increasingly useful in establishing the diagnosis. Treatment requires wide surgical excision with removal of involved regional lymph nodes. Opinions are divided regarding the use of postoperative irradiation or chemotherapy. Records of all patients with sebaceous carcinoma of the head and neck treated at UCLA Medical Center, los angeles, over the last 35 years were reviewed. The clinical and pathologic features are discussed, and the literature is summarized.

19/91. Extraocular sebaceous carcinoma in a patient with muir-torre syndrome.

    BACKGROUND: Sebaceous carcinoma is a rare, aggressive neoplasm that arises from the adnexal epithelium of sebaceous glands and is commonly associated with muir-torre syndrome. OBJECTIVE: The metastatic potential of extraocular sebaceous carcinoma warrants a thorough evaluation to establish the extent of disease. methods: We describe a 55-year-old man who presented with an asymptomatic abdominal wall mass 3 years after definitive diagnosis of muir-torre syndrome. RESULTS: A biopsy of the surgical specimen revealed sebaceous carcinoma. CONCLUSION: Dermatologists are crucial to the early recognition and diagnosis of extraocular sebaceous carcinoma. In our patient with documented muir-torre syndrome, continued surveillance allowed for prompt recognition and treatment of this associated cutaneous malignancy.

20/91. Lymphadenoma lacking sebaceous differentiation in the parotid gland.

    Sebaceous lymphadenoma is a rare salivary gland neoplasm that is composed of solid or cystic sebaceous elements in a dense lymphoid background. An even rarer tumor resembling sebaceous lymphadenoma but without the sebaceous element has also been recognized. This unusual tumor has been named "lymphadenoma lacking sebaceous differentiation" (LLSD) or simply "lymphadenoma". Because of the rarity of this entity, detailed clinicopathological manifestations have not been properly characterized. We report a case of LLSD occurring in the left parotid gland of a 49-year-old man. Histologically, the tumor was well circumscribed and composed of solid squamous islands within dense lymphoid stroma. No sebaceous differentiation could be identified in the epithelial nest. The similarity of the histological picture of the tumor to metastatic carcinoma may lead to misdiagnosis. It is therefore important for the pathologist to be aware of the distinguishing features of this unusual entity.
