Eccrine spiradenoma of the upper extremity: case report and an algorithm for management

Sonographic Findings of an Eccrine Spiradenoma

“…1-3 It presents at any stage of life, with men and women being equally affected. 1,3 An eccrine spiradenoma is round, spongy or firm, cutaneous, and single or multiple and can range in size from 1 to 10 cm. 3 In some cases, this tumor shows color changes such as red or purple and can be painful.…”

“…1,3 An eccrine spiradenoma is round, spongy or firm, cutaneous, and single or multiple and can range in size from 1 to 10 cm. 3 In some cases, this tumor shows color changes such as red or purple and can be painful. 4 The pain accompanying this tumor has been attributed to the vast nervous plexus that surrounds the connective tissue capsule.…”

“…5 At surgery, the tumor is typically well defined, without involvement of underlying structures. 3 Sweat glands are of 3 types: eccrine, apocrine, and mixed. Eccrine glands produce a clear aqueous secretion without releasing part of the secreting cell.…”

Sonographic appearance of an eccrine spiradenoma: A case report

“…Surgery should be followed by close and routine follow-up examinations to rule out local recurrence. 4…”

Spiradenoma causing longitudinal splitting of the nail

“…ES has never been observed on glabrous skin, as it is an undifferentiated or poorly differentiated benign adnexal neoplasm; however, both ES and cylindroma can sometimes display tubular differentiation with a ‘decapitation’ pattern, as would be expected in an apocrine neoplasm . The most recent hypothesis is suggestive of an abnormal multipotent stem cell in the folliculosebaceous–apocrine unit …”
