Cutaneous plasmacytosis: an unusual presentation sharing features with POEMS syndrome?

Cutaneous plasmacytosis is a recently described skin disorder consisting of brown to red papules and nodules containing polyclonal plasmacytes. In this particular case, leg ulcers developed but also a diffuse patchy hyperpigmentation coexisting with a primary hypothyroidisim. The last two signs have only been described to date in POEMS syndrome, which is linked to monoclonal plasmacytic proliferation, and might suggest an overlap between these two entities.

Necrobiosis lipoidica and silicotic granulomas on Muller's phlebectomy scars.

We report an unusual case of concomitant necrobiosis lipoidica and silicotic granulomas in scars of phlebectomies on the legs, suggestive of a Koebner phenomenon.

Angiosarcoma of the scalp. A case with a particularly aggressive evolution.

A 80-year-old woman presented with a spontaneously bleeding wound on her scalp. The diagnosis of angiosarcoma was made based on histopathological examination of the second biopsy 1 month later. At that time, a large hematoma was present on the scalp and forehead with two bleeding erosions and numerous small blue-black nodules as well as a right cervical lymphadenopathy. The patient was treated by wide-field electron-beam radiotherapy, which showed no effect. The particularly aggressive evolution of this angiosarcoma led to death within less than 2 months.

Targetoid hemosiderotic hemangioma.

A new case of hemosiderotic targetoid hemangioma is reported. The literature is briefly reviewed.

Mycetoma of the foot due to Fusarium sp. treated with oral ketoconazole.

We report the case of a 30-year-old Nigerian patient with mycetoma of the foot without bone involvement caused by Fusarium sp..Long-term administration of ketoconazole produced a significant improvement with good clinical and biological tolerance.

Neutrophilic eccrine hidradenitis.

We report an additional typical case of neutrophilic eccrine hidradenitis, which was observed in a 57-year-old man with acute myelogenous leukemia. He developed this eruption following chemotherapy with cytarabine and mitoxantrone. A short review of the literature is presented.

Senile erythroderma with serum hyper-IgE.

A case of senile erythroderma with serum hyper-IgE is presented. It is comparable to 8 cases previously described by Japanese authors.

Tufted angioma.

The clinical and histological description of 2 cases of tufted angioma is presented.

Delayed skin reaction caused by a coelenterate.

We report a delayed skin reaction, histologically characterized by liquefaction degeneration of the basal layer, which was observed in a 30-year-old man returning from Guadeloupe. It was most likely due to contact with a marine animal.

[Acquired reactive collagen disease in the adult: successful treatment with UV-B light]. / Erworbene reaktive Kollagenose des Erwachsenen: erfolgreiche Behandlung durch UV-B-Licht.

A 77-year-old patient with diabetes and progressive renal failure suffered from severe pruritus accompanied by umbilicated, keratotic papules corresponding clinically and histologically to reactive perforating collagenosis. UV-B light therapy considerably improved the pruritus and the skin lesions.

Melanoacanthoma of the penis shaft. Report of a case.

We report an additional case of melanocanthoma, a rare benign mixed tumor of both keratinocytes and melanocytes occurring in a 66-year-old man on the penis shaft, a localization not previously described. Clinical and histological features are briefly discussed.

Generalized eruptive pustular drug rash due to cephalexin.

A 38-year-old woman developed a generalized pustular eruption 18 h after taking an oral cephalosporin (cephalexin). After having excluded other possible pustular dermatoses, we concluded that our patient's eruption was drug-induced.

Acute pseudoseptic arthritis and palmoplantar pustulosis.

The case of a 60-year-old woman who developed acute peripheral arthritis of a pseudoseptic character (high synovial leucocytosis and fever) associated to a palmoplantar pustulosis is reported.

[Developmental aspects of nevus spilus: review of the literature apropos of 7 cases]. / Les aspects evolutifs du naevus sur naevus: revue de la littérature à propos de 7 observations.

The nevus on nevus is a dischromic lesion with a double component made of a pigmented, pale-brown coloured spot, most often congenital punctuated by macular or discretely papular darker elements, with a usually later setting-up and conventionally characterized by an absence of evolutivity. A series of seven cases is reported of whom three present a very peculiar evolution: A 37 years old man is taking a medical advice for a nevus on a congenital nevus on the right buttock on which appeared later on a blue-coloured, lightly sensitive nodule which clinically calls to mind the diagnosis of a blue nevus: the surgical exeresis is refused by the patient. A little girl, born in 1972, has since her birth a nevus on nevus of her right fore-arm; in 1975 and 1976 appeared successively on this lesion three nodules evocative of Spitz melanoma (fig. 4), which are surgically removed; histologic examination confirms the clinical diagnosis (fig. 5). A woman, aged 38, presents a big nevus on congenital zosteriform nevus of the right lower limb; since 1982, one of the dark elements situated on the lower third of the leg is progressively spreading and becoming polychromic (fig. 6); the clinical suspicious of superficial spreading malignant melanoma is confirmed by the histologic examination. In the literature, the terminology aiming to call this kind of nevic pale brown spot recovered by darker macules is not quite clear, as it was already emphasized by Stewart in 1978 (27). Indeed, numerous different denomination are found in it: "nevus spilus", nevus on nevus", "spotty nevus" "speckled lentiginous nevus", "speckled nevus "spilus".(ABSTRACT TRUNCATED AT 250 WORDS)
