Subungual exostosis of the third toe.

Subungual exostosis is a variant of osteochondroma that appears as a pinkish nodule under the free end of the nail plate. It becomes symptomatic when large enough to disrupt the overlying nail on the digit or through mechanical irritation of the exostosis from physical activity. Appropriate workup of such a lesion is important, because many cases of subungual exostosis are initially misdiagnosed by a variety of specialists, including dermatologists. With the use of history and roentgenography, subungual exostosis can be effectively diagnosed or excluded. Appropriate treatment of subungual exostosis can be selected- surgical excision of the lesion with significant cure rates achieved. Although most cases of subungual exostosis are localized to the great toe, we describe a 32-year-old woman who developed a subungual exostosis on her right third toe. Appropriate diagnostic workup and surgical treatment of the right third-toe exostosis has resulted in complete relief of symptoms with no signs of recurrence 7 months after surgery.

Pruritus of unknown origin: a retrospective study.

BACKGROUND: Pruritus of unknown origin is a common complaint, and systemic causes must be considered. However, there is little data on how frequently systemic causes are responsible or whether any patient characteristics make a systemic cause more likely. OBJECTIVE: We attempted to determine how frequently pruritus of unknown origin had a systemic etiology in an outpatient population seen in a university dermatology department and whether any patient characteristics made a systemic explanation more likely. METHODS: This is a retrospective study using chart reviews and telephone interviews to collect data. RESULTS: Of 50 patients, 11 had a systemic cause of pruritus. Pruritus was the initial symptom of systemic disease in 7 of these patients. No patient characteristics were statistically associated with systemic causes of pruritus. CONCLUSION: Pruritus of unknown origin was the initial symptom of a systemic disease in 7 of 50 patients presenting to a dermatology clinic with this complaint. The underlying diseases included hypothyroidism, gastric adenocarcinoma, hepatitis C, HIV, laryngeal carcinoma, graft-versus-host disease, and chronic lymphocytic leukemia.

A painful cutaneous nodule as the presentation of metastatic transitional cell carcinoma of the renal pelvis.

We report a 43-year-old man with HIV who presented with a painful, vascular-appearing nodule as the initial manifestation of metastasis of a prior transitional cell carcinoma of the renal pelvis. The transitional cell carcinoma had been treated by nephroureterectomy 4 years before the appearance of the nodule. Histopathologic comparison of the nodule with the prior transitional cell carcinoma and immunoperoxidase staining with monoclonal antibodies confirmed that the nodule was a metastasis of the original transitional cell carcinoma. In general, metastasis of transitional cell carcinoma to the skin is quite uncommon. This case is the first reported episode of transitional cell carcinoma of the renal pelvis metastasizing to the skin in the form of a vascular-appearing nodule. The significance of this unusual metastasis occurring in a person with HIV is unknown.

Remission of psoriasis after treatment with interferon-alfa and 2-chlordeoxyadenosine for hairy cell leukemia.

2-Chlordeoxyadenosine (2-CdA) is an antineoplastic/immunosuppressive agent used to treat hairy cell leukemia (HCL), chronic lymphocytic leukemia, and low-grade lymphomas. Its immunomodulatory properties, however, may allow its future use in the treatment of psoriasis. We report a patient with psoriasis and HCL who was treated for 1 week with continuous intravenous infusion of 2-CdA for recurring HCL. Both the psoriasis and the HCL cleared. Four years after 2-CdA treatment, the patient has psoriasis on only 1% of his body surface area. 2-CdA induces lymphocytopenia, which may explain the improvement in this patient's psoriasis.

Olmsted syndrome. Case report and identification of a keratin abnormality.

BACKGROUND: Olmsted syndrome is a rare disorder characterized by a mutilating palmoplantar keratoderma and periorificial keratotic plaques. It begins in early childhood and is complicated by the development of painful flexion contractures, constrictions, and autoamputations of the digits. Only 11 cases of Olmsted syndrome have been reported to date. However, no biochemical abnormalities in the skin were reported in any of these cases. OBSERVATIONS: We report the 12th case of Olmsted syndrome. In addition, we describe a keratin abnormality found in a skin specimen obtained from our patient. The specimen showed a suprabasilar staining pattern with AE1, an antibody that shows only basilar staining in normal skin. CONCLUSION: We report the 12th case of Olmsted syndrome, review the literature, and describe a keratin abnormality that was found in our patient's skin specimen.

Widespread eruptive dermal and atypical melanocytic nevi in association with chronic myelocytic leukemia: case report and review of the literature.

Eruptive nevi have been associated with local skin trauma and immunosuppression, and atypical eruptive nevi preceding melanoma have been reported in immunocompromised transplant patients. We describe a 25-year-old man with widespread eruptive atypical and dermal melanocytic nevi in association with chronic myelocytic leukemia. Our patient's disease differs from earlier reports of eruptive nevi because his nevi appeared before induction chemotherapy. Eruptive nevi may have been a prodrome to leukemia in this patient. His nevi were histologically similar to eruptive atypical nevi observed in AIDS patients and may imply a link between systemic immunosuppression and melanocyte proliferation. We suggest that patients in whom eruptive nevi develop in association with immunosuppression should be carefully observed for the development of melanoma skin cancer.
