Multiple familial eccrine spiradenoma with cylindroma

Eccrine Spiradenoma of the Scalp

Eccrine spiradenoma is an uncommon benign adnexal tumor originating from the eccrine sweat gland. We diagnosed a eccrine spiradenoma on a 55-year-old man with histopathologic confirmation upon biopsy followed by complete resection, who had visited our clinic with a chief complain of occipital scalp mass. The solitary eccrine spiradenoma occurring in the scalp is rarely to be seen and should be considered as a differential diagnosis for a solitary cystic mass of the scalp.

A serpentine inside eccrine spiradenoma: a new trichoscopic sign

Trichoscopy being an in vivo technique aids in magnification of cutaneous structures with appropriate pattern and color. A female presented with erythematous tumor on scalp. Histopathology showed features of eccrine spiradenoma. Authors evaluated trichoscopic patterns in eccrine spiradenoma. It demonstrated specific trichoscopic pattern in the form of linear red structure appearing as ‘serpentine’.
