Thrombotic vasculopathy associated with cryofibrinogenemia.
Cryofibrinogenemia refers to the presence of cold-precipitable plasma proteins associated with a variety of disorders, including malignancies, inflammatory processes, and thrombohemorrhagic phenomena. Few cases of essential or primary cryofibrinogenemia are reported. We report a case in a 48-year-old man of essential cryofibrinogenemia and hemorrhagic necrosis of the ears and of the upper and lower extremities. Histopathologic studies demonstrated extensive eosinophilic thrombi in the dermal vasculature, with minimal inflammation and no vasculitis. Cryofibrinogenemia should be considered in the investigation of patients with otherwise unexplained cold intolerance and dermal thrombosis associated with minimal or no inflammation.

Cutis verticis gyrata.
When the scalp exhibits folds and furrows resembling gyri, it is termed cutis verticis gyrata. The possible etiologies may be categorized as primary essential, primary nonessential, and secondary cutis verticis gyrata. This is based on history, physical examination, and histologic criteria with or without laboratory examinations.

Hydroquinone-induced localized exogenous ochronosis treated with dermabrasion and CO2 laser.
Exogenous localized ochronosis can result from the repeated use of hydroquinone-containing creams, many of which are available over the counter. We report a case that was managed by dermabrasion and CO2 laser. The incidence and proposed etiologies of hydroquinone-induced exogenous ochronosis are reviewed.

The thyroid.
The integument contains many components whose function is influenced by thyroid hormone. Thus, an increase or decrease in hormone levels results in a variety of cutaneous, hair, and nail changes. These changes are important to recognize, as they may aid in the early diagnosis of thyroid disorders. Other cutaneous disorders are more prevalent in patients with thyroid disease, and their recognition may likewise be helpful. Finally, several syndrome complexes occur with which thyroid disorders are regularly associated.

Heightened cutaneous reactions to mosquito bites in patients with acquired immunodeficiency syndrome receiving zidovudine.
Three patients with acquired immunodeficiency syndrome noted changing cutaneous reactions to mosquito bites one to three months after starting zidovudine therapy. Enhanced T-cell function is one possibility for the heightened response to mosquito bites in these patients.

Nevus sebaceus associated with major ophthalmologic abnormalities.
Nevus sebaceus rarely occurs as part of a syndrome consisting of central nervous system and ophthalmologic abnormalities. We describe a case of nevus sebaceus associated with an epibulbar complex choristoma and colobomas of the optic disc and peripapillary choroid, and review the dermatologic, ophthalmologic, and neurologic literature on the nevus sebaceus syndrome. When associated with other developmental abnormalities, nevus sebaceus and epidermal nevus have erroneously been considered to be a single entity. In this article, we delineate and emphasize the ophthalmologic abnormalities associated with the nevus sebaceus syndrome.
