Giant eccrine acrospiroma.

Abstract

Four cases of large eccrine acrospiroma (three benign, one malignant) are reported. The benign tumors involved the lower extremities of two women and one man (73 to 89 years of age). The duration of the lesions ranged from 10 to 20 years. The malignant tumor involved the left side of the chest of a 60-year-old man. Its occurrence in a lesion that had been present for 40 years suggested malignant transformation of a pre-existing benign eccrine acrospiroma. Each tumor showed little to no cellular atypia. Mitotic rates (mitotic figures per 10 high-power fields) varied both between and within lesions. Average mitotic rates did not differentiate the benign from the malignant tumors. The most important distinguishing features of large benign eccrine acrospiromas are the relative circumscription, the lack of cellular atypia, and the absence of stromal, perineurial, and angiolymphatic invasion.

Parotid acinar cell carcinoma in a long-term survivor of childhood acute lymphoblastic leukemia.

Secondary malignancies are an important cause of morbidity and mortality in childhood cancer survivors. Salivary gland tumors account for about 6% of the second cancers. The majority of these are mucoepidermoid carcinomas (MEC) of the parotid gland. We report the clinical and pathological features of a rarer histological type, acinic cell carcinoma (ACC), in a childhood acute lymphoblastic leukemia (ALL) survivor. The behavior of secondary ACC appears similar to primary tumor and similar treatment may be adopted. Early recognition and complete resection is important for achieving a good outcome. Careful monitoring for recurrence or a third malignancy is needed.

Nodular hidradenocarcinoma over the parotid gland: a pathologic presentation.

BACKGROUND: Nodular hidradenocarcinoma (NHAC), an eccrine carcinoma, has been reported in the dermatology and pathology literature, but few references have been made in the otolaryngology literature even though the head and neck is a common site of occurrence. METHODS: A case report of a 37-year-old Hispanic man with a right-sided neck mass diagnosed preoperatively as a parotid mass by imaging and fine-needle aspiration is presented. After presentation at our multidisciplinary tumor board, excision of the mass was undertaken. RESULTS: Final pathology revealed a NHAC, which is presented in our report. CONCLUSION: NHAC is an aggressive malignant tumor that is often misdiagnosed preoperatively and that must be treated with aggressive multimodality therapy for increased survival.

Metastatic hidradenocarcinoma with demonstration of Her-2/neu gene amplification by fluorescence in situ hybridization: potential treatment implications.

A 44-year-old man was referred for a right chest nodule of 3 months duration. A 'benign' nodule had been excised from this location 8 years prior. On examination, palpable nodes were noted in the right axilla. Radiographic studies were significant only for right axillary lymphadenopathy. Histologically, a nodular dermal proliferation composed of poorly differentiated epithelioid cells in nests and focally forming ducts with pseudopapillary architecture comprised the primary tumor. Features of a clear cell hidradenoma were noted focally. Immunohistochemical (IHC) analysis revealed reactivity for HMW cytokeratins, CK5 and CK7, p53, p63, CEA (focal), androgen receptor, EGFR, estrogen receptor (ER), MUC5AC, and strong/diffuse membranous staining for Her-2/neu. Negative stains included villin, TTF-1, CDX2, S-100 protein, vimentin, gross cystic disease fluid protein 15 (GCDFP-15), mammoglobulin, and MUC2. A wide local excision and axillary node dissection was performed. Metastatic tumor involved nine of 28 nodes. Interphase fluorescence in situ hybridization (FISH) demonstrated chromosomal amplification of the Her-2/neu locus within the tumor and a nodal metastasis. The patient has completed adjuvant and radiotherapy, including trastuzumab, and is asymptomatic. We believe this to be the first demonstration of Her-2/neu amplification in a malignant skin adnexal tumor. In analogy to breast carcinoma, these findings suggest the applicability of trastuzumab for patients with metastatic adnexal carcinomas demonstrating Her-2/neu amplification.
