Multiple eccrine hidrocystomas associated with Graves' disease

Histological study of eyelid hidrocystoma: A clinical case

Hidrocystomas are benign lesions with frequent localization on the eyelids and common appearance as isolated translucent cystic lesions. The multiple and bilateral localization has been associated with systemic diseases or epidermodysplasia. The histological and ultrastructural study contributes to the distinction in eccrine or apocrine. In this clinical case, multiple bilateral skin lesions of the eyelids were removed surgically from a 55-year-old male patient with free medical history. The lesions were fully removed surgically without rupture of the cysts. The obtained tissues were fixed and prepared for an anatomical pathology study as well as observation under the electron microscope. The histological study revealed cystic lesions with low cuboid epithelium and presence of cells and collagen fibrils, while the ultrastructural study also revealed the presence of apoptotic and secretory cells as well as vacuolization of the cytoplasm. No relapse of the lesions was obtained. In conclusion, the histological and ultrastructural study of multiple hidrocystomas can highlight special features that help to better classify and diagnose eccrine or apocrine hidrocystomas, while surgical removal without rupture of the cyst can prevent reappearance.

Eccrine hidrocystoma in a child: an atypical presentation

Eccrine hidrocystomas are small benign cystic lesions that normally affect only adult females. Eccrine hidrocystoma is characterized by tense vesicles that are predominately located on the face and particularly on the periorbital areas. Histologically, eccrine hidrocystoma consists of one or more partially collapsed unilocular cysts in the dermis, and these cysts are often situated adjacent to normal eccrine ducts. An 8-year-old boy presented with multiple skin-colored to bluish tiny papules on his nose. Histopathologically, the dilated partial cystic structures in the middermis were lined by one or two layers of flattened or cuboidal epithelial cells. We report here on an atypical presentation of multiple eccrine hidrocystomas that were localized on the nose of a child.

Multiple eccrine hidrocystomas

The clinical and pathological features and treatment of two patients with multiple eccrine hidrocystomas are presented. The first case is characterized by multiple pearly papules with a bluish hue located in the periorbital region and the bridge of the nose. The second case is characterized by multiple, skin-coloured papules located in the periorbital area, forehead, chin and nose. Both were exacerbated by a hot and humid environment. Histopathologically, both demonstrated a unilocular cyst located in the dermis, with a 2-3-layer wall composed of cuboidal epithelium that was non-keratinizing. Treatment with topical atropine sulphate 1% in aqueous solution three times a day was instituted in the first case; however, this was poorly tolerated because of blurred vision and nausea. The lesions were subsequently hyfrecated with a good response. The second case was treated with topical atropine sulphate 1% in aqueous solution three times a day with a good response.
