Syringocystadenoma Papilliferum: An Unusual Presentation

Abstract

Syringocystadenoma papilliferum is a benign hamartomatous adnexal tumour. Most of the patients present with solitary lesions in the head and neck region at birth or in early childhood. Multiple lesions are rarely seen and those which arise outside the head and neck region are even more uncommon. A case of syringocystadenoma papilliferum with multiple verrucous lesions and which was located in the right flank, an unusual site, has been presented.

A red nodule of the scalp

“…A possible derivation from eccrine or undifferentiated pluripotential cells has also been reported [ 1 – 4 ]. SCAP affects males and females equally [ 2 ], developing at birth (50% of cases) or in childhood/adolescence [ 3 , 5 ]. At puberty a dimensional growth may be displayed [ 2 , 3 ].…”

“…SCAP affects males and females equally [ 2 ], developing at birth (50% of cases) or in childhood/adolescence [ 3 , 5 ]. At puberty a dimensional growth may be displayed [ 2 , 3 ]. SCAP usually arises on the scalp, face and neck, and less commonly on other regions, such as the trunk, eyelids and genitalia [ 2 – 4 ].…”

“…At puberty a dimensional growth may be displayed [ 2 , 3 ]. SCAP usually arises on the scalp, face and neck, and less commonly on other regions, such as the trunk, eyelids and genitalia [ 2 – 4 ]. Clinically it appears as a hairless, smooth, or verrucous single papule or plaque, but multiple elements may occur, especially on SN [ 2 – 4 ].…”

Clinically it appears as a hairless, smooth, or verrucous single papule or plaque, but multiple elements may occur, especially on SN [ 2 – 4 ]. SCAP may also be associated with different types of lesions, both benign (viral warts, SN, apocrine poroma, hidradenoma papilliferum) and malignant (basal cell carcinoma, sebaceous carcinoma) [ 2 , 3 ].…”

Syringocystadenoma Papilliferum: A Rare Tumor in an Unusual Location

“…Most of the patients present with solitary lesions. Multiple lesions are usually associated with naevus sebaceous (3,5). SCAP is also associated with linear naevus verrucosus, apocrine poroma, apocrine hidrocystoma, tubulopapillary hidradenoma, hidradenoma papilliferum, papillary eccrine adenoma, apocrine acrosyringeal keratosis, poroma folliculare, linear naevus verrucosa, atypical fibroxanthoma, clear cell syringoma, basal cell epithelioma, sebaceous epithelioma, trichoepithelioma, verruca vulgaris, and naevus comedonicus.…”
