CEA: Carcinoembryonic antigens EP: Eccrine poroma E ccrine poroma (EP) is a benign neoplasm of the eccrine terminal duct, composed of epithelial cells that show tubular differentiation. EP often presents as a reddish nodule with a predilection for the distal extremities. This report describes a lesion with the clinical and dermoscopic findings of a seborrheic keratosis. However, histopathologic...
Aims. Hidrocystomas are benign cystic growths of the apocrine and eccrine sweat glands. These cystic lesions have been well documented on the face, head, and neck, but rarely in the external auditory canal. Presentation of Case. A 67-year-old woman presented with a bluish cystic mass partially occluding the external auditory canal and interfering with hearing aid use. Lesion was excised complet...
Background: Non pigmented eccrine poroma is a benign tumor that can have dermoscopic features mimicking malign neoplasias. The characteristic vascular pattern of this tumor hasn’t been established. We found a scarcely reported vascular pattern, which can be useful to distinguish this tumor from malignant ones and propose a new nomenclature to these vessels due their similarity with the common c...
Eccrine hidrocystomas are rare lesions, cysts, or benign tumors, which lead to bilateral deformities in the eyelid areas. Several treatments are described in the literature. However, none of them has been established as the gold standard. Hence, it becomes necessary to consider the contribution of different opinions and available resources to clinical evaluation. A 73-year-old female patient pr...
Eccrine angiokeratomatous hamartoma is a rare newly defined vascular lesion of the skin, the first case of which was reported in 2006 (Kanitakis J, Ly A, Claudy A. Eccrine angiokeratomatous hamartoma: a new variant of eccrine hamartoma with angiokeratoma. J Am Acad Dermatol 2006; 55: S104-6). On web Literature Search, Only three previously documented cases of the lesions were found. A 1.5-year-...
We report here a case of adenolipoma of the skin, an unusual variant of lipoma, arising on the neck. A 56-year-old man visited our hospital due to an anterior neck mass. An excisional biopsy was performed. The mass revealed a tan-yellow soft cut surface. We could not find any difference from other lipoma on gross inspection. Microscopically, the mass showed proliferation of mature adipocytes ad...
Neutrophilic eccrine hidradenitis (NEH) is a nonspecific clinicopathological reaction pattern, classified as a neutrophilic dermatosis, that usually develops in patients receiving chemotherapy for a hematologic malignancy. More rarely, it has been reported in association with infectious agents such as Serratia and Enterobacter species, Staphylococcus aureus, and human immunodeficiency virus. We...
Eccrine porocarcinoma is a rare malignant tumor. Immunostain for S-100 protein, in addition to epithelial membrane antigen (EMA) and carcinoembryonic antigen (CEA), is described to be useful in the diagnosis. Herein, we report a case of eccrine porocarcinoma with immunostain for S-100 protein which was useful in diagnoses of recurrent and metastatic lesions. The primary lesion in the left ingui...
Objective Neurofibromatosis type 1 (NF1) causes neural and cutaneous disorders and reduced exercise capacity. Exercise/heat exposure increasing internal temperature must be compensated by eccrine sweat function and warmed skin vasodilation. We suspected NF1 could adversely affect eccrine sweat function and/or vascular thermoregulatory responses (VTR). Methods The eccrine sweat function and VT...
