Lymphangioma circumscriptum: a case report

Lymphagioma circumscriptum (LC), also known as microcystic lymphatic malformation, is thought to arise from muscular lymphatic cisterns that failed to segment during embryonic development. Clinically, this pathology manifests as red, pink, or black scattered aggregates of small, thin-walled, translucent vesicles, giving it the classic appearance of “frog-spawn on the skin.” Some lesions exhibit overlying hyperkeratosis, resulting in a verrucous appearance. Histologic examination of superficial lesions reveals solitary or grouped cystically dilated lymph vessels located within the papillary dermis. Management remains a challenge while surgical excision is regarded as the most definitive treatment with lowest rates of recurrence, but has the highest risk of complications. Other treatments reported in literature include electrodessication, Laser, Imiquimod cream, percutaneous drainage, and sclerotherapy.

It comes in threes: A case of syringocystadenoma papilliferum associated with tubular apocrine adenoma and verruca in the axilla of a Filipino female

Syringocystoadenoma papilliferum (SCAP) is a benign adnexal tumor usually located in head and neck. The occurrence of SCAP in the axilla is uncommon. The occurrence of SCAP coexisting with two other histopathological types of tumors in one cutaneous lesion is unusual.  We presented the case of a syringocystoadema papilliferum associated with tubular apocrine adenoma (TAA) and verruca.

A case study of Clear Cell Acanthoma in a 69 year old Filipino female patient

Clear cell acanthoma is an uncommon benign epidermal tumor usually seen in the 60-80 year old age group and presenting in the lower legs. In the Philippines there has by far been one reported case of the disease (Philippine Dermatologic Society-Health Information System). We present a case of clear cell acanthoma in a Filipino female.

Pigmented trichoblastoma in a Filipino patient: a report of clinicopathologic and dermoscopic features*

Trichoblastoma is an uncommon benign neoplasm largely composed of follicular germinative cells. Pigmented trichoblastoma or a melanotrichoblastoma is a rare variant with only few reported cases in the literature.

Topical treatments for seborrheic keratosis: a systematic review

Seborrheic keratosis is a benign epidermal tumor commonly seen in the sun-exposed skin of adults. Current treatment modalities are invasive, which include electrodessication, cryotherapy, or surgery. Alternative options such as topical therapy may be beneficial to patients who have contraindications to standard treatment, or to those who prefer a non-invasive approach. However, evidence supporting the use of topical agents is lacking.
