RESUMEN
Lymphangiomas are congenital lymphatic malformations and cutaneous lymphangioma circumscriptum is the most common type. It is clinically characterized by clusters of translucent vesicles and the presence of dermoscopically yellow lacunae surrounded by pale septa, as well as reddish to bluish lacunae. In our case, the recently described hypopyon-like feature manifested, aiding in the sometimes difficult differential diagnosis of cutaneous lymphangioma circumscriptum with vascular lesions, further highlighting the importance of dermoscopy in what can be a diagnostic challenge.

BACKGROUND: Increasing rates of non-melanoma skin cancer support the use of prosthetic materials for the closure of post-surgical defects with cartilage or bone involvement. The use of allografts, especially titanium, is well established in maxillofacial procedures but is uncommon in dermatologic surgery. METHODS: A 92-year-old man presented with a basal cell carcinoma measuring 2×3 cm on the right cheek. Computed tomography showed infiltration of the anterior maxillary sinus wall. The tumor was excised under general anesthesia. The final defect comprised skin, muscle, the central portion of the maxillary bone and part of the maxillary sinus mucous. The defect was closed with titanium mesh and covered with a rotation flap from the right cheek. The secondary defect created by the preauricular rotation was closed with a free skin graft from the supraclavicular area. RESULTS: The use of titanium mesh enabled satisfactory esthetic and functional results to be achieved safely and quickly. CONCLUSIONS: Titanium mesh facilitates the repair of large defects and avoids the second intervention and increased risk for infection associated with bone grafting. Reconstruction with titanium mesh is considered a valuable technique in post-trauma fractures and post-oncologic defects but remains underused in dermatologic surgery. The present experience supports its use as a reliable option in bone replacement.

Molluscum contagiosum (MC) lesions on the face are mainly observed in HIV patients and are related to low CD4 cells counts. We report a 41-year-old female patient infected with human immunodeficiency virus who had a CD4 count of 22 cells/mm³. She developed molluscum contagiosum lesions at the right upper eyelid. Skin biopsy was performed to exclude other serious conditions, such as dimorphic fungal infections. A good response was observed with three sessions of curettage and topical application of 70 percent trichloroacetic acid. Facial molluscum contagiosum lesions can be a cutaneous marker of severe immunosuppression in HIV patients and skin biopsy is important in ruling out the diagnosis of dimorphic fungal infections.
