Zosteriform skin involvement of nodal T-cell lymphoma: a review of the published work of cutaneous malignancies mimicking herpes zoster.

A 77-year-old Japanese woman initially presented with non-Hodgkin's lymphoma involving her neck, axillary and inguen lymph nodes. She had edematous erythema and nodules limited to the skin in zosteriform distribution on the left side chest wall along the T4-5 dermatome. In addition, since 1970, we have mainly been collecting English-language articles on malignant skin tumors and skin metastasis described as zosteriform in the title, and we have reviewed a total of 29 cases, including our own. It should be mentioned that 59% of the cases reported had been diagnosed with herpes zoster at the time of the initial examination and that many of them had received drug therapy (e.g. acyclovir). We wish to add the dermatomic eruption mimicking zoster sine herpete to the list of possible presentations of cutaneous malignancies.

Cyclosporine A as treatment of esophageal involvement in dermatomyositis.

We report a case of a 70-year-old man with dermatomyositis complicated by esophageal involvement resistant to corticosteroid therapy. It had serious and potentially life-threatening implications, resulting in impossible oral feeding. This condition was successfully resolved by administration of cyclosporine A.

Hyperkeratotic lichenified skin lesion of gluteal region.

Elderly people may develop typical skin lesions on the superior part and both sides of the anal cleft. Although such skin changes have recently been reported as anosacral cutaneous amyloidosis in primary cutaneous amyloidosis, in our histopathological examinations no amyloid deposition has been detected at the sites of these lesions. Because hyperkeratosis, acanthosis and follicular plugging were seen in all of the cases histopathologically, we think that these skin manifestations are essentially a type of keratinization abnormality instead. We consider this disease to be a type of senile skin change that develops in response to prolonged mechanical irritation.

Treatment of osmidrosis using the ultrasonic surgical aspirator.

Numerous surgical methods have been introduced to treat osmidrosis. However, many problems with wound healing have been reported, including haematoma, seroma, skin necrosis and severe scarring. Ultrasound energy liquefies sweat glands via cavitation, but minimally affects blood vessels and nerves at the same energy level. Our patient was treated with ultrasonic surgical aspiration, which allowed the effective removal of the apocrine glands with little scarring. The ultrasonic surgical aspirator offers a safe and effective method to treat osmidrosis with few complications. This is the operation of first choice, especially for the patients who are sensitive about their surgical scars.

Eosinophilic pustular folliculitis (Ofuji disease) manifested as pustules on the palms and soles.

Eosinophilic pustular folliculitis (EPF) is clinically characterized by eosinophilic follicular papulopustules that form annular configurations on the face, trunk, and extremities. We describe a case of a patient whose EPF manifested on the soles of the feet, an area that normally does not contain hair follicles. The patient experienced a dramatic therapeutic response to indomethacin.

Multiple eruptive dermatofibromas: a review of the literature.

In this review we summarize the characteristic features of multiple eruptive dermatofibromas based on an analysis of cases in the literature. Many researchers have reported multiple eruptive dermatofibromas diagnosed using the definition of "multiple" as the presence of at least 15 lesions. However, this criterion is arbitrarily chosen and might not be entirely valid for all cases. A more precise definition may include the eruption of several multiple eruptive dermatofibromas reported within a short period of time. Because more than half of the patients with multiple eruptive dermatofibromas have underlying diseases, and more than 80% of the underlying diseases are immune-mediated, multiple eruptive dermatofibromas could possiblv be considered as a partial manifestation of an immune-mediated disease. This underscores the possibility of early diagnosis of immune-mediated diseases in patients with multiple eruptive dermatofibromas.
