This manual explains the mathematical theory, construction, and use of a general purpose Matlab package for solving Laplace's equation for planar problems.

Frictional asymptomatic darkening of the extensor surfaces (FADES), also known as hyperkeratosis of the elbows and knees, is commonly seen by dermatologists but has never been well characterized. Patients present with uniform, asymptomatic, brown darkening over the extensor surfaces of the elbows and knees with minimal scaling. Both frictional stress and family history may play a role in the pa...

Pityriasis versicolor (PV) is a superficial mycoses caused by lipophilic fungus; Malassezia yeast. Dermoscopy can be used as complementary tool for assessing PV, but histopathology confirmatory, whenever results of KOH (potassium hydroxide) examination are inconclusive. There dearth Indian data on the findings dermoscopy and PV. To find correlation between dermoscopic histopathological features...

In 1906 Jadassohn and Lewandowsky described a rare genodermatoses named it pachyonychia congenita. Pachy means thick. It is group of involving keratin mutation with thickened nails variable associated findings. Pachyonychia congenita disease having four types. However, type 1 2 can be considered common among them. often mimic fungal infection as nail hyperkeratosis occur in both.

Phrynoderma is a type of follicular hyperkeratosis attributed to various nutritional deficiencies, most notably vitamin A. We report a case of a 31-year-old mentally-deficient man who was a resident of a voluntary welfare nursing home. He presented with characteristic hyperkeratotic follicular papules on his trunk in a setting of low serum level of vitamin A and malnutrition. Although commonly ...

Circle hairs (CHs) represent a body hair growth disorder which is characterized by asymptomatic presence of hairs in typical circular or spiraliform arrangement. It is not associated with follicular or inflammatory abnormalities. CHs are rarely reported, probably underestimated, as medical consultation for CH only is rare in practice. It needs to be differentiated from rolled hairs, which is a ...

Epidermolytic acanthoma is a rare benign tumour, which may occur in both isolated and disseminated forms. Only seven cases of disseminated epidermolytic acanthoma (DEA) have been described. This entity should be distinguished from other hereditary or acquired conditions which involve epidermolytic hyperkeratosis and other benign acanthomas. On the basis of the clinical history and the histologi...

Epidermolytic acanthoma (EA) is a benign cutaneous condition. It is characterized by warty or flat-topped, keratotic papules that show epidermolytic hyperkeratosis in histology. EA has been described to occur in various locations, namely the trunk, face, and genitoscrotal area. However, it has not been previously reported to involve the palmar area. To the best of our knowledge, we present the ...
