Acquired ichthyosis is an uncommon disease which is characterized by symmetric scaling of the skin. Acquired ichthyosis has been described in association with a variety of underlying causes, including malignancies, drugs, infections, endocrine, metabolic and autoimmune diseases. Acquired ichthyosis associated with diabetes mellitus has been reported only in one case. We report the case of a new-onset diabetes mellitus with a one-month history of generalized acquired ichthyosis and palmoplantar keratoderma corroborated with skin biopsy, which completely disappeared after regulation of blood glucose levels with insulin therapy.
Methotrexate (MTX) is an effective but potentially toxic treatment for psoriasis. We describe a patient who administered 20 mg daily of MTX for 5 d and presented with ulcerated and necrotic lesions on the psoriatic plaques, mouth erosions and hair loss. However, his psoriatic plaques and ulcerations totally healed rapidly within two weeks and no recurrence has been observed for the 6 months of follow up.
We report a case of woolly hair nevus with pigmentary demarcation lines and heterochromia iridis. Woolly hair nevus is a rare abnormality of the scalp hair characterized by the patch of hair, which is curlier and light colored than the rest of the scalp hair. Association of woolly hair nevus with some other ectodermal defects effecting skin and eyes has been reported before. Here, woolly hair nevus associated with demarcation lines and heterochromia iridis, to our knowledge, have not been previously reported.
Onychomadesis is separation of the nail plate from the nail matrix due to arrest of nail growth for a certain period. Here we describe two patients with onychomadesis on the hands after varicella infection. To our knowledge, this is the first case of onychomadesis reported after varicella infection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
