Vulvar syringomas in a 9-year-old child with review of the literature

Case series of rare nonvenereal vulvar dermatoses

Nonvenereal vulvar diseases such as syringoma and vestibular papillomatosis can be difficult to differentiate from genital warts. Misdiagnosis of these conditions can lead to improper treatment without significant improvement and prolonged suffering. Histopathology may differentiate these conditions from sexually transmitted diseases and help in appropriate treatment. Here, we present case series of four rare vulvar diseases.

Vulvar syringoma: A rare cause of pruritus vulvae

Syringomas commonly occur in women over the face, neck, and chest. They are usually asymptomatic and mainly of cosmetic concern. The vulva is an uncommon site for syringomas. A 45-year-old woman had asymptomatic lesions over the face, of 28 years duration and presented with vulvar papules, associated with severe pruritus for the past 2 months. Clinical and histopathological examination confirmed them to be syringomas. Coexistent facial and vulvar syringomas are rare. Further, vulvar syringomas presenting as pruritus vulvae is still rarer. We report a case with severe pruritus vulvae causing sufficient distress to seek medical care, which is remarkably unusual.

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.

Milia with calcium deposits on the palms and soles in a patient with multiple syringoma

An 8-year-old girl was referred for evaluation of multiple lesions on the neck, axillae, and genitalia. A great number of milia-like lesions were also noticed on the palms and discrete keratotic plugs on the soles. Histopathology from lesions on the neck, axilla, and vulva were consistent with syringoma. On the palms and soles, eccrine ducts cystically dilated filled with proteinaceous material and calcifications were found. Although the nature of palmar and plantar lesions in our patient is uncertain, we think that they should be related to the other syringomas on her skin.
