摘要:

ABSTRACT:A 3‐month‐old child with a grossly symmetrical monomorphic papular acral‐located skin eruption, a voluminous lymphadenopathy post‐BCC vaccination, and hepatomegaly was seen. The diagnoses of Gianotti‐Crosti's syndrome and generalized tuberculous infection have been discarded. The appearance of these lesions 48 hours after a tuberculin patch test, their tuberculoid structure, and the absence of any systemic involvement favored the diagnosis of papular tuberculids, a rarely reported complication of BCC va

摘要:

ABSTRACT:Light‐sensitive dermatoses do not constitute a major problem among the black people in Nigeria. In a 10‐year study, only 64 cases (about 0.4% of all dermatologic patients) had light‐sensitive dermatoses. Seven of the JO patients with endogenous photodermatoses were albinos. Two patients with polymorphic light eruption were visiting Caucasians. Only one normally pigmented black Nigerian had xeroderma pigmentosum. Fifty‐four patients bad photodermatoses from exogenous causes, of which hydroquinone‐induced exogenous ochronosis constituted the largest group of patients. Two women had estrogen‐induced porphyria cu

摘要:

ABSTRACT:In a study of cutaneous leishmaniasis (CL) caused by Leishmania major in Saudi Arabia, 10% of the patients were found to have subcutaneous nodules (5CN). The SCNs were usually inconspicuous, painless, and proximal to the primary skin lesions; when multiple, they showed a “sporotrichoid” configuration or appeared as “beaded cords.” Their number ranged from 1–16 (average 3.25 ± 2.50; mean ± 1 SD). In some patients, the SCNs seemed to be triggered by antileishmanial treatment. The clinical picture and pathologic findings suggest, that SCNs in patients with CL represent lymphatic dissemination, a phenomenon not widely

摘要:

ABSTRACT:Ninety‐eight families with leprotic members were examined. Of these, only two families were identified where both couples were leprotic. The father was the known leprotic member in 46 cases and the mother in 12 families. There were seven cases where the father and one son were leprotic, while in one case it was the mother and son; 25 families presented a leprotic son or daughter, while their parents were apparently free. Leprotic siblings or cousins of nonleprotic parents were seen in five families.The duration of marriage and details of history were taken in each case. The relation between close contact and the development of leprosy will be discusse

摘要:

ABSTRACT:We compared morphologic features of Keratohyalin granules (KHG) that were directly related to keratinization in oral mucosa (tongue, cheek, gums, palate; n = 4) with those in parakeratotic epidermis (psoriasis, n = 2; pityriasis rubra pilaris, n = 1; acute dermatitis, n = 1) and normal or‐thokeratotic epidermis. Among others, the ultrastructural features of globular KHG were observed in the cheek, nonspecialized tongue mucosa, and parakeratotic epidermis occurring in psoriasis, pityriasis rubra pilaris, and acute dermatitis, whereas gums and palate showed a mixture of characteristics, also resembling stellate KHG as seen in normal skin.From literature as well as from our studies, the impression was gained that globular KHG were found especially in quickly dividing epithelia and could easily be distinguished from the irregular or stellate KHG that were found in slowly dividing normal epidermis.Therefore, we studied keratinization features on days 3, 7, and 14 after autografting normal human skin (n = 4), thus inducing high cell turnover. Stellate KHG, present in granular cells of normal skin, were almost absent on the third day. Active cell division on the seventh day resulted in sparse keratohyalin formation inside globular granules of low electron density, whereas numerous, rather electron‐translucent lipid droplets occurred in upper spinous and horny cells. These two phenomena seemed to be interrelated. After 14 days, round and increasingly electron‐dense KHG were noted. In more differentiated areas, KHG became irregular. The morphogenesis of KHG could be studied in the subsequent phases of differentiation in autologous skin grafts.We conclude that the ultrastructural features of KHG formation are related to the speed of cell turnover in the epidermis as well as in the oral m
