Two rare manifestations of melanomas: generalized cutaneous melanosis and rapid solar induction of showers of small pigmented lesions. A critical review of the literature and presentation of two additional cases.
Lerner AB, Moellmann G.
Two unusual patients with metastatic melanoma are presented. One had generalized melanosis, and the other a rapid induction of multiple small pigmented lesions within a day of exposure to the sun. From a variety of clinical observations on these 2 patients and ones reported in the literature, and from recent advances in basic biomedical knowledge, we conclude that in both conditions the anomalous ...

Behçet's disease: a review and a report of 12 cases from Sweden.
Ek L, Hedfors E.
In a retrospective study of 12 patients with Behçet's disease, more than half were found to originate from the Near East, where the prevalence of the disease is known to be high. The immigrant patients were all males, whereas 3 of the 5 patients with Swedish ancestry were females. Certain differences emerged between the two groups, including different sex ratio and absence of HLA B5 association a ...

Cutaneous T cell lymphoma of signet ring cell type: a specific clinico-pathologic entity.
Vaillant L, Monégier du Sorbier C, Arbeille B, de Muret A, Lorette G.
We describe a new case of signet ring cell peripheral T cell lymphoma in a 45-year-old man. This lymphoma had a very indolent course, since--without treatment--the clinical staging has shown no evidence of disease progression 11 years after initial symptoms. Immunophenotype indicated pan T antigens (Leu 4 CD3, Leu 1 CD5) and T suppressor cytotoxic antigen (IOT8 CD8) expression. Several T antigens ...

Interaction between tachykinins and CGRP in human skin.
Wallengren J, Wang ZY.
Substance P (SP), neurokinin A (NKA) and calcitonin gene-related peptide (CGRP) coexist in nerve fibres in the skin. CGRP causes erythema upon intracutaneous injection. The erythema is independent of axon reflexes and release of mast cell histamine. SP is known to produce a flare reaction that is dependent on axon reflexes and release of mast cell histamine. The flare reaction to NKA is known to d ...

Evidence of increased keratinocyte proliferation in air-liquid interface cultures of non-bullous congenital ichthyosiform erythroderma.
Amsellem C, Haftek M, Hoyo E, Thivolet J, Schmitt D.
Modern pharmacological and dermatological research requires the use of appropriate in vitro models which permit a faithful reproduction of various aspects of the in situ situation. The air-exposed culture of keratinocytes on dead de-epidermized dermis is one of the best models of in vitro epidermal differentiation known at the moment. In this study, we verified the model's validity for the reprodu ...

Effect of a single exposure to in vivo UVB radiation on the allogeneic mixed lymphocyte reaction of spleen cells.
Kitajima T, Imamura S.
We investigated the effect of a single exposure to in vivo UVB radiation on the splenic T cell alloreactivity and antigen presenting cell (APC) function needed for alloantigen presentation. Splenic T cells from UVB-irradiated C57BL/6 mice were used as responders, and spleen cells from UVB-irradiated BALB/c mice were used as stimulators for a source of APCs in mixed lymphocyte culture. A single UVB ...

Intensity and area increase of UVB-induced erythema: two variables used for studies of the influence of topically applied drugs.
Juhlin L, Shroot B.
The area of UV erythema produced by a small beam head was found to increase with increasing doses. The aim was to investigate whether measurement of the area could be a more useful indicator of UV-induced damage than classic visual grading. Topical pretreatment with all-trans retinoic acid (tretinoin) and betamethasone valerate was used to test the applicability of the method in pharmacological st ...

Scintigraphic diagnosis of syphilitic lesions in rabbits by radiolabelled monoclonal antibodies specific for Treponema pallidum.
Lee MG, Chung KY, Lee JD, Shin JS, Whang KK, Awh OD, Kim SJ, Lee JB.
Immunoscintigraphy with radiolabelled monoclonal antibodies has been widely used to detect solid tumours. The purpose of this study was to investigate its potential for the specific localization of syphilitic lesions. F(ab')2 fragments were prepared from murine monoclonal antibodies against Treponema pallidum produced in our laboratory and labelled with 131I. Bilateral testicular infections were c ...

The trichogram as a prognostic tool in alopecia areata.
Peereboom-Wynia JD, Beek CH, Mulder PG, Stolz E.
The value of the trichogram as a prognostic tool in alopecia areata was investigated in 93 patients with not more than three lesions on the scalp. Evaluation of the clinical features was one year later. In each patient, two regions were investigated: the margin of one of the lesions and the control region. In 80% of the patients with a normal trichogram at the margin of the lesional hair at the fi ...

Amelanotic acral melanoma masquerading as fibrous histiocytic tumours. Three case reports.
Hara M, Kato T, Tagami H.
We report 3 cases of amelanotic melanoma developing on the finger, whose histology disclosed dermal invasion of histiocyte-like tumour cells. One of the 3 cases was subungual melanoma and the other 2 were on the volar surface of the finger tip. Because of the characteristic dense infiltration of large histiocyte-like tumour cells, including many multinucleated giant cells, we initially considered ...

Solid basal cell epithelioma (BCE) possibly originates from the outer root sheath of the hair follicle.
Asada M, Schaart FM, de Almeida HL Jr, Korge B, Kurokawa I, Asada Y, Orfanos CE.
The presence and distribution of several cytokeratins (CKs) in 20 solid basal cell epitheliomas (BCEs) were investigated and compared with the pattern of CKs in normal epidermis, perilesional skin and in the outer root sheath (ORS) of the human hair follicle. Tissue samples were stained with monoclonal antibodies (MoAbs) against human CKs, using the APAAP technique. Additionally, CK profiles were ...

Cutaneous mesenchymal tumour with haemangiopericytoma-like features.
Larbre B, Kanitakis J, Sarret Y, Gavaud C, Faure M, Thivolet J.
A case of cutaneous mesenchymal haemangiopericytoma-like tumour affecting a 17-year-old male is presented. Clinical features were non-specific. The tumour was studied by light, electron microscopy and immunohistochemistry. The results of these studies suggested the diagnosis of a mesenchymal, poorly-differentiated tumour showing features of haemangiopericytoma. The clinical course after surgery wa ...

Mitosis of mast cells in skin lesions of atopic dermatitis.
Sugiura H, Uehara M.
Mitoses of mast cells with cytoplasmic granules were observed in 6 out of 55 skin lesions of atopic dermatitis. It is thus likely that the local proliferation process of mast cells contributes to the increased number of mast cells in skin lesions of atopic dermatitis. Mitotic mast cells with cytoplasmic granules were also observed in 2 out of 8 dinitrochlorobenzene contact dermatitis lesions provo ...

Treatment of psoriasis vulgaris with topical calcipotriol has no short-term effect on calcium or bone metabolism. A randomized, double-blind, placebo-controlled study.
Mortensen L, Kragballe K, Wegmann E, Schifter S, Risteli J, Charles P.
The purpose of this double-blind, placebo-controlled study was to examine whether the vitamin D analogue calcipotriol, topically applied to psoriatic skin lesions, had any effect on calcium or bone metabolism. Thirty-four outpatients with psoriasis vulgaris were randomized to treatment with either calcipotriol ointment (50 micrograms/g) or vehicle ointment twice daily for 3 weeks. The patients wer ...

Levels of terbinafine in plasma, stratum corneum, dermis-epidermis (without stratum corneum), sebum, hair and nails during and after 250 mg terbinafine orally once per day for four weeks
Faergemann J, Zehender H, Denouël J, Millerioux L
The distribution of terbinafine in stratum corneum dermis-epidermis (without stratum corneum), sebum, hair, nails and plasma was studied in human male volunteers during and after 250 mg orally once daily for 28 days. The highest concentration was seen in sebum, 56.07 micrograms/g, after 14 days of therapy. The concentration was still 1.0 microgram/g 44 days after stop of medication. In stratum cor ...
