Abstract

Nodular hidradenoma was diagnosed in a 29-month-old girl on her axilla. Hidradenoma, sometimes designated as acrospiroma, is a benign sweat gland neoplasm, which mostly occurs in adults. Very few cases of hidradenoma have been documented in children in their first decade of life. This case demonstrates that when a child develops a skin nodule, nodular hidradenoma can be a diagnostic option.

Figure

• 

  Fig. 1 Multiple exophytic and verruciform nodules of about 2 cm in diameter with well-vascularized surface located on the left axilla.

• 

  Fig. 2 Ultrasonographic finding reveals well-defined ovoid hypoechoic mass at the subcutaneous layer with several small internal cystic areas.

• 

  Fig. 3 (A) Microphotograph shows solid and partially cystic mass in dermis. No connection was found between the lesion and epidermis (H&E stain, ×100). (B, C) Microphotograph shows polygonal cells with eosinophilic to clear cytoplasm in both solid and cystic areas (H&E stain, ×200). (D) Microphotograph shows ductal differentiation. Hyalinization of fibrous stroma is identified (H&E stain, ×400).
