Basal Cell Carcinoma: Basic Facial Anatomy
The most important genetic syndrome associated with the development of BCCs is the nevoid BCC syndrome. This syndrome is inherited in an autosomal dominant fashion and is caused by a…
Dermatology
Spitz Nevus
Treatment: Complete excision for a classic Spitz nevus is curative and allows for a complete histological evaluation. Indeterminate lesions should be reexcised with conservative margins to make sure they have…
Reticulohistiocytoma
Treatment: Solitary reticulohistiocytomas are cured with a simple elliptical excision. They rarely recur. Patients with multicentric reticulohistiocytosis require systemic therapy. Screening and constant vigilance for an underlying malignancy is required…
Seborrheic Keratosis
Treatment: These keratoses require no therapy. If they become inflamed or irritated, a simple shave biopsy removal is curative. Cryotherapy and curettage are often used to treat these benign skin…
Porokeratosis
Histology: On biopsy, the hallmark of porokeratosis is recognition of the cornoid lamella. The cornoid lamella is the pathological representation of the hyperkeratotic peripheral rim of tissue seen on clinical…
Pyogenic Granuloma
Treatment: Most pyogenic granulomas resolve after shave removal and curettage with cautery of the base of the lesion. These tumors do have a propensity to recur, and occasionally an elliptical…
Pilar Cyst (Trichilemmal Cyst)
Treatment: Simple surgical excision is curative. The recurrence rate is minimal. These cysts typically are removed very easily after excision through the overlying skin into the cyst wall. The cyst…
Palisaded Encapsulated Neuroma
Treatment: Complete excision is diagnostic and curative. The tumors rarely recur after elliptical excision. They have no malignant potential, and patients can be reassured that they do not have any…
Osteoma Cutis
Pathogenesis: Primary forms of osteoma cutis show intramembranous ossification that is centered within the dermis. There is no preceding cartilage formation to act as a scaffolding for the bone to…
Nevus Sebaceus
Treatment: If treatment is undertaken, complete surgical excision is the treatment of choice. This not only removes the lesion but also removes the risk of malignant potential. Another approach is…
