SUMMARY We report a rare case of cystic eccrine spiradenoma in the finger. A 46-year-old man presented with a cystic mass in his left index finger. Clinical assessment along with the investigation pointed toward a diagnosis of a ganglion. However, excisional biopsy of the mass revealed histopathological findings of cystic eccrine spiradenoma. Very few cases of eccrine spiradenoma have been repo...

Eccrine syringofibroadenoma is a rare adnexal tumor of eccrine ductal differentiation with variable clinical features. It manifests as either a solitary or multiple papules and nodules arranged in a symmetrical or linear pattern. The anatomical distribution is wide and includes the face, trunk, extremities, and rarely the nails. Histopathological findings show anastomosing cords and strands of ...

We describe a healthy 69-year-old Japanese man with generalized neutrophilic eccrine hidradenitis (NEH). He visited our outpatient clinic with a 15-year history of disseminated pruritic papules on his trunk and extremities; the eruptions, however, were limited to the summer months. Histological findings reveal a dense accumulation of neutrophils around the sweat glands with degenerated secretar...

Giant Vascular Eccrine Spiradenoma (GVES) is a rare variant of Eccrine Spiradenoma (ES), a tumor that develops from the sweat gland. It differs from Eccrine Spiradenoma in its larger size and vascularity as well as propensity for bleeding and ulceration, which may cause a clinical misdiagnosis of vascular lesion or malignant tumor. All previously reported cases in English literature have been i...

Eccrine Poroma is a rare benign adnexal tumor. It presents the problem of differential diagnosis with several entities. Dermoscopic features are suggestive and may guide diagnosis. We report new observation. A 44-year-old woman, presented an asymptomatic lesion on dorsal side left foot for 2 years. Clinically nodule was brownish, well delimited superficial erosions, firm palpation. Dermoscopy s...

Eccrine poroma is a rare benign adnexal tumor of epithelial cells originating from the terminal ductal portion of the sweat glands that is typically located on palms and soles, although other cutaneous sites can be affected [1]. It is usually nonpigmented even if there is a pigmented variant that corresponds to 17% of cases and it is usually underdiagnosed, since it is mistakenly confused with ...

BACKGROUND Appendageal skin tumors belong to a heterogenous group of tumors with specific histopathology. The aim of this study is to determine the pattern of appendageal tumors in skin biopsies done in our department. METHODS This is a 3-year retrospective descriptive study of all patients who were diagnosed to have skin appendageal tumors in our department, and the diagnoses were confirmed ...

Eccrine syringofibroadenoma is a rare benign adnexal neoplasm derived from cells of the acrosyringium of eccrine sweat glands. ESFA usually manifests as a solitary nodule on the extremities of elderly patients, but it may also present as papules, nodules or plaques. Its clinical appearance is nonspecific and malignant neoplasms should be considered in the differential diagnosis. However, histop...

The aim of this article is to highlight the importance of Eccrine Spiradenoma (ES) in the differential diagnosis of chronic soft tissue lesions of the foot. These include a broad spectrum of nonneoplasm lesions, as well as benign and malignant neoplasms. Benign tumours include deep fibromatosis, neurogenic tumours, lipoma, haemangioma, synovial proliferations, and exceptionally rare on foot, sk...
