1/124. Prominent hyperkeratotic plantar and palmar warts.We report the case of a 28-year-old man who had prominent hyperkeratotic plantar and palmar warts, and flat warts on his face and chest. By dna hybridization, human papillomavirus 1 and/or 2, and 3 dna were detected from the tissues of these skin lesions. Results of laboratory investigations revealed leukopenia, eosinophilia, anti-HBs antigen and anti-hepatitis c virus antibody, and decrease in the OKT4/OKT8 ratio. He had no abnormality in cellular immunity. He was treated with multiple modalities, but was successfully treated with electrocautery to the plantar and palmar warts, and cryotherapy with liquid nitrogen to the flat warts. Nine years after the initial treatment, almost no recurrence was recognized.- - - - - - - - - - ranking = 1keywords = plant (Clic here for more details about this article) |
2/124. Keratosis palmoplantaris varians of Wachters.We report a case of hereditary palmoplantar keratosis (HPPK) causing a progressive reduction of the prehension capacity of the fingers due to the presence of hyperkeratotic lesions which had appeared approximately 25 years earlier. These lesions, also involving the soles, appeared yellowish in color, linear or round in shape, symmetrical and often confluent, developed prevalently at the pressure points displaying a non-transgrediens pattern. The histological examination, clinical picture and careful analysis of the literature enabled us to define this form as 'keratosis palmoplantaris varians of Wachters'. As a contribution to a conclusive HPPK classification we discuss the differential diagnosis of this disorder most commonly identified through nummular-linear keratoses also known as Siemens' syndrome.- - - - - - - - - - ranking = 1keywords = plant (Clic here for more details about this article) |
3/124. alstroemeria L. (Peruvian lily).Alstroemerias are one of the most common plants that cause allergic contact dermatitis in floral workers. This colorful plant has gained great popularity among florists and their patrons. This concise review will help dermatologists to gain familiarity with this plant and show how to diagnose problems that it may cause.- - - - - - - - - - ranking = 0.5keywords = plant (Clic here for more details about this article) |
4/124. costello syndrome with decreased glucose tolerance.We report a case of costello syndrome, which is an uncommon multisystemic condition with cutaneous manifestations on the palms and soles. In the literature there are 29 cases described, all the studies are published in the genetic literature with a few exceptions. We add a further case associated with impaired glucose tolerance. The diagnostic clinical signs are impressive, and highly characteristic. Cutaneous manifestations are: loose skin of the hands and feet "washer woman's hand", hyperkeratosis palmoplantaris, curly or sparse hair, acanthosis nigricans, papillomata nasi. Coarse, progeroid facial features with a bulbous nose, feeding difficulties in infancy, cardiac involvement with cardiomyopathy or conduction defect, and in our case impaired glucose tolerance also presented. Postnatal growth retardation, mental retardation, and a distinctive friendly personality is characteristic. Hyperextensible fingers with broad distal phalanges and joint contractures were observed, and peroneal hypertonicity required treatment by achilles tendon lengthening. The decreased glucose tolerance is interesting in the view of the acanthosis nigricans. No storage disease and no chromosomal abnormality were observed. Only in one case is a balanced translocation described in the literature.- - - - - - - - - - ranking = 0.16666666666667keywords = plant (Clic here for more details about this article) |
5/124. onychomycosis caused by Scytalidium dimidiatum. Report of two cases. review of the taxonomy of the synanamorph and anamorph forms of this coelomycete.The authors report two cases of onychomycosis in the dystrophic form, one of them involving an hiv-positive patient, provoked by Scytalidium dimidiatum, previously called Scytalidium lignicola. The subject is reviewed from the taxonomic viewpoint, considering the anamorph Hendersonula toruloidea as a synonym of Nattrassia mangiferae, and having Scytalidium dimidiatum as the major synanamorph. According to many mycologists, Scytalidium hyalinum may be a separate species or a hyaline mutant of Scytalidium dimidiatum. Scytalidium lignicola Pesante 1957 was considered to be the type-species of the genus by ELLIS (1971)13 and later to be a "conidial state" of Hendersonula toruloidea by the same author, today known as Nattrassia mangiferae. The microorganism lives only on the roots of certain plants (mainly Platanus and pinus). It produces pycnidia and is not considered to be a pathogen, although it is considered as a possible emerging agent capable of provoking opportunistic fungal lesions. The importance of this topic as one of the most outstanding in fungal taxonomy, so likely to be modified over time, as well as its interest in the field of dermatologic mycology, are emphasized.- - - - - - - - - - ranking = 0.16666666666667keywords = plant (Clic here for more details about this article) |
6/124. Alkaptonuric ochronosis presenting as palmoplantar pigmentation.We describe a 37-year-old woman who presented with palmoplantar pigmentation, thickening and pitting of 4 years duration. Bluish pigmented patches were seen over the sclera of her eyes. Her lumbar spine showed typical calcification of the intervertebral discs. Addition of Benedict's reagent to a urine sample of the patient gave rise to greenish brown precipitate and brownish black supernatant. Alkalinization of urine turned it black. A biopsy of the palmar lesion demonstrated irregular breaking up, swelling and homogenization of collagen bundles in the reticular dermis. Yellow-brown (ochre coloured) pigment was seen lying within the collagen bundles and also freely in the deeper dermis confirming our clinical diagnosis of alkaptonuric ochronosis. To the best of our knowledge this is probably the second report of alkaptonuria presenting with palmoplantar pigmentation.- - - - - - - - - - ranking = 1keywords = plant (Clic here for more details about this article) |
7/124. Squamous cell carcinoma arising from lesions of porokeratosis palmaris et plantaris disseminata.We report a 63-year-old Japanese man with numerous hyperkeratotic papules of porokeratosis palmaris et plantaris disseminata (PPPD) who developed multiple squamous cell carcinomas on the lesional sites of the palms and soles. The hyperkeratotic papules, which showed tightly packed columns of parakeratotic cells in the cornified layer (cornoid lamella), lost granular layer, and dyskeratotic keratinocytes in the epidermis below the cornoid lamella histologically, had been noticed on the palms and soles from the age of 28 and 43, respectively. He has no family history of such hyperkeratotic papules. Treatment with etretinate (10-50 mg/day) was given discontinuously, and the total dose of etretinate amounted to approximately 21 g over 14 years (average: 0.07 mg/kg/day). He noticed erosions on the hyperkeratotic papules on the left sole and palm more than 9 months after cessation of treatment with etretinate. Histological findings showed numerous atypical keratinocytes in the epidermis and upper dermis with mononuclear cell infiltration seen in the upper dermis. The diagnosis of squamous cell carcinoma arising from the lesions of porokeratosis palmaris et plantaris was made. Five erosions with histologically malignant changes were removed 1 cm from the margin of the erosions. These findings suggest that etretinate may have an inhibitory action on malignant changes in PPPD.- - - - - - - - - - ranking = 1keywords = plant (Clic here for more details about this article) |
8/124. Contact dermatitis to Asparagus officinalis.A 53-year-old farm worker presented with a 3-year history of an occupational allergic contact dermatitis to asparagus. The dermatitis cleared quickly with courses of systemic corticosteroids but relapsed within days of further exposure to asparagus. The genera Asparagus is made up of some 300 species. It belongs to the family liliaceae which includes tulips, onions and garlic. Asparagus contains asparagin, coniferin and the glucoside vanillin. The allergen may be a plant growth inhibitor, 1,2,3-Trithiane-5-carboxylic acid, which is present in young shoots.- - - - - - - - - - ranking = 0.16666666666667keywords = plant (Clic here for more details about this article) |
9/124. Idiopathic palmoplantar eccrine hidradenitis in children.Idiopathic palmoplantar eccrine hidradenitis (IPPH) is a recently described disorder characterized by painful erythematous plantar nodules and in three cases, showed a typical neutrophilic infiltrate around and within the eccrine sweat apparatus. Five cases of IPPH on the soles of the feet in healthy children are reported. The disorder presented after intense physical activity in four cases. The course was benign and self-limiting. Complete bed rest for several days without any medical therapy led to alleviation of the pain and disappearance of all the lesions. Conclusion. Idiopathic palmoplantar eccrine hidradenitis may be more common than reported. Paediatricians should be aware of it in order to avoid unnecessary diagnostic tests and treatments.- - - - - - - - - - ranking = 1.1666666666667keywords = plant (Clic here for more details about this article) |
10/124. Fingertip dermatitis in a retail florist.prevalence of plant contact dermatitis in retail florists varies with exposure, and the number of reports of contact allergy to cut tulips is rather small. Alpha-methylene-gamma-butyrolactone is better known as the cause of both alstroemeria dermatitis in retail florists and tulip finger in wholesale floral workers who handle the bulbs. Our patient presented with prominent erythema, scaling, and peeling of the skin of the thumb, index, and middle fingers of his right hand. Results of a patch test to alpha-methylene-gamma-butyrolactone were strongly positive, and the patient determined that the exposure had occurred when he stripped leaves from the tulip stems to arrange cut flowers. Other natural sources of the antigen include alstroemeria; Bomarea; dioscorea hispida; Erythronium; Gagea; fritillaria; and at least one species of onion, allium triquetrum.- - - - - - - - - - ranking = 0.16666666666667keywords = plant (Clic here for more details about this article) |
