Acne fulminans (AF) is a rare severe form of acne vulgaris associated with systemic symptoms. It primarily affects male adolescents. Although the aetiology of AF remains unknown, many theories have been advanced to explain it. There have been reported associations with increased androgens, autoimmune complex disease and genetic pre-disposition. The disease is destructive, with the acute onset of painful, ulcerative nodules on the face, chest and back. The associated systemic manifestations such as fever, weight loss and musculoskeletal pain are usually present at the onset. The patients are febrile, with leucocytosis and an increased erythrocyte sedimentation rate. They may require several weeks of hospitalization. The treatment of AF has been challenging; the response to traditional acne therapies is poor. The recommended treatment is aggressive and consists of a combination of oral steroids and isotretinoin. To avoid the relapses, duration of such treatment should not be less than 3-5 months. Although the prognosis for patients treated appropriately is good, these acute inflammatory nodules often heal with residual scarring.

Solar ultraviolet light electromagnetic waves are a known environmental carcinogenic agent closely associated with the development of skin cancer in light-complexioned individuals. Outdoor workers have higher annual exposure to ultraviolet light. We will review the topic of actinic keratoses among these individuals as this common rudimentary form of superficial cutaneous squamous cell carcinoma is explored in greater detail.

Oculocutaneous albinism represents a group of inherited skin disorders characterized by a generalized reduction of cutaneous, ocular and pilar pigmentation from the time of birth. Oculocutaneous albinism types 1 and 2 are the most common, but several other types have been described. A defect in the melanin synthesis pathway, resulting in reduced formation of melanin, is responsible for oculocutaneous albinism. Aetiology, clinical manifestations, diagnosis and management are discussed.

The Muir-Torre syndrome of sebaceous neoplasms of the skin, with or without keratoacanthomas, and multiple low-grade visceral malignancies with prolonged survival is a rare disorder. Colonic polyps are frequently present, and the syndrome appears to be familial. We report 2 unrelated patients with the Muir-Torre syndrome. Each case exhibited sebaceous adenomas. Gastrointestinal findings included colonic adenocarcinomas and a tubulovillous adenoma. Although an unusual disease, the Muir-Torre syndrome requires recognition because these patients are at risk for multiple primary malignancies and may have family members also at risk.

We report a patient with a large apocrine hidrocystoma. These tumors are almost always under 10 mm in diameter. In this 40-year-old man the tumor measured 20 mm. Apocrine hidrocystoma must be considered when evaluating a patient with a large cystic lesion of the face. Surgical management is similar to that of other benign cystic lesions of this region.

The Brooke-Spiegler syndrome is an autosomal dominant one characterized by cylindromas, trichoepitheliomas and occasionally spiradenomas. Within a given family, some members may have cylindromas whereas others may have trichoepitheliomas or both. We describe the coexistence of trichoepithelioma papulosum multiplex (also known as epithelioma adenoides cysticum of Brooke) and cylindromas in a 30-year-old man, and discuss the relationship between these two autosomal dominant syndromes.
