Syringomas on the penis

Evaluation and management of the patient with multiple syringomas: A systematic review of the literature

Syringomas are benign adnexal tumors with distinct histopathologic features, including the characteristic comma ("tadpole") shaped tail comprised of dilated, cystic eccrine ducts. Clinically, syringomas typically present in adolescent females predominantly in the periorbital region. They may present as solitary or multiple lesions, and more rare sites of involvement include the genitals, palms, scalp, and the chest. Over the past 50 years, there have been >800 reported cases of syringoma either alone or in conjunction with a systemic syndrome, most commonly Down syndrome. The primary aim of this systematic review is to discuss the clinical features and associations of syringomas with a focus on the patient with multiple syringomas. Its secondary aims are to explore pathophysiology with a focus on multiple syringomas and provide comprehensive data on both traditional and novel treatments. Importantly, multiple syringomas present across a broad clinical spectrum. Though noted in many textbooks to be related to tumor syndromes, the association of syringomas with inherited tumor syndromes is only rarely reported in the literature. Despite multiple reported cases of syringoma, the pathophysiology remains poorly understood and treatment continues to pose a significant challenge.

Cutaneous syringoma: a clinicopathologic study of 34 new cases and review of the literature

BACKGROUND

Syringoma is a benign adnexal tumor derived from intraepidermal eccrine duct.

AIM

The aim of the study is to report the experience concerning syringoma by reviewing the clinical and histopathologic features of a series of 34 histologically diagnosed syringoma patients observed over a period of six years.

MATERIALS AND METHODS

Thirty-four patients were sorted into two groups, localized and generalized syringoma, according to the Friedman and Butler classification. Different histopathologic findings were recorded in specially designed questionnaires for further analysis.

RESULTS

Ninety-seven percent of the patients were females with the mean age of 27.6 years. The mean duration of the lesions before the presentations was six years. The diagnosis of syringoma was only considered in 23 patients (67.6%) and was the initial diagnosis in only 13 (38.2%) patients. All histological findings were seen more common in our cases. in comparison to the documented cases in the literature. Clear cell change of epithelial eccrine cells was 85.2% and there was no difference in the histopathological findings in the two groups. Our patients with generalized syringoma (GS) had a considerable lower age of onset than the ones with localized syringoma (LS) (P = 0.027).

CONCLUSION

Our patients with generalized syringoma were younger than the ones with localized syringoma. Distribution of the generalized syringoma was mainly in the chest and neck followed by the forearms whereas localized syringoma was mostly confined to the face, axilla and genitalia. There were also some conditions associated with our cases including sarcoidosis, calcinosis cutis and basal cell carcinoma.

Syringoma of the moustache area

Syringomas are benign tumors of the eccrine ducts that appear as small skin-colored or yellow papules. They usually occur in the periorbital area, but have also been found on the scalp, forehead, cheeks, axillae, abdomen, extremities, genitalia, and buttocks. We describe a patient with an unusual presentation of syringomas on the moustache area.
