Introduction: Methotrexate is being given by dermatologists in only extreme cases of skin disorders such as in severe Psoriasis Vulgaris. Strict precautionary measures are done to avoid its well-known adverse effects. An early but less common sign of its toxicity are painful erosions on plaques. Methotrexate is an effective but potentially toxic treatment for different severe dermatologic disorders such as in severe Psoriasis Vulgaris. Meticulous and complete history-taking, physical examination and laboratory work-up to come up with a correct diagnosis as well as, knowledge of indications for treatment, proper dosing, folate supplementa-tion, monitoring, proper referral and early detection of its toxicity are important in order to avoid cutaneous and systemic adverse effects including death. Case Report A case of a 57-year old male with a 2-day history of painful erosions on plaques on both upper and lower extremities after eleven days of taking Methotrexate 2.5mg/tablet one tablet three times a day without folate supplementation. He was then being treated by a general physician as a case of Psoriasis Vulgaris. He was subsequently admitted under the Internal Medicine service due to epigastric pain, nausea, anorexia, generalized body weakness and passage of black tarry stools. He was referred to the Department of Dermatology for the painful erosions on plaques. He expired two days after admission due to Acute Respiratory Failure. Post-mortem Skin punch biopsy was done and revealed chronic eczematous dermatitis consistent with Lichen Simplex Chronicus with superimposed drug induced hypersensitivity reaction.

This is a case of an 11-year-old male who presented with multiple neurofibromas with hypertrichosis. Classic cutaneous neurofibromas, café-au-lait macules, axillary freckling, Lisch nodules, and scoliosis were also present fulfilling a diagnosis of Neurofibromatosis type 1. This is the first report of multiple neurofibromas with hypertrichosis in the Philippines. Hypertrichosis overlying a neurofibroma is rarely reported and the mechanism remains to be elucidated.
