Despite its frequency, there are inadequate information detailing its incidence and prevalence. This subsequently leads to lack of comprehensive POH classification and stratification of impact on an individual's general well'being.

A retrospective review of methotrexate-induced hepatotoxicity among patients with psoriasis in a tertiary dermatology center in Malaysia.

Background: Methotrexate (MTX) is a common and efficacious systemic agent used for the treatment of moderate to severe psoriasis. Nevertheless, its use is associated with the risk of hepatotoxicity. This study was performed to study the association of MTX dose with regards to hepatotoxicity as evidenced by deranged transaminases.

Bullous pemphigoid in an elderly patient with myelodysplastic syndrome and refractory anemia coupled with excess of blast.

Bullous pemphigoid (BP) has a recognized association with solid organ tumors, but is relatively rare in hematological malignancies. We report a 67-year-old male who developed BP after being diagnosed with myelodysplastic syndrome and refractory anemia with excess of blast (RAEB). Skin biopsy elucidated sub-epidermal bulla using direct immunofluorescence, revealing linear C3 and IgG deposits along the basement membrane.
