Imatinib mesylate--Gleevec (US), Glivec (worldwide), STI571--is an oral cancer drug that selectively inhibits several protein tyrosine kinases associated with human malignancy. The drug is used for the treatment of chronic myeloid leukemia, malignant gastrointestinal stromal tumors, and some other conditions. Treatment with imatinib is generally well tolerated but not without the risk of adverse effects. The risk of severe adverse events is low. Cutaneous side effects of this drug are common but muco-cutaneous lichenoid eruption with nail changes is very rare. We report a case of lichenoid eruption during imatinib therapy involving the skin, mucous membranes, and nails that cleared in spite of ongoing imatinib therapy.
Angiokeratoma is a dark violaceous keratotic papule which can be solitary or multiple. Generalised systemic angiokeratoma constitute angiokeratoma corporis diffusum, a rare X-linked recessive inborn error of glycosphingolipid metabolism due to deficiency of alpha galactosidase A. Patients with this disease have premature death due to the vascular complications. A case of possible Fabry's disease is presented.
