Abstract
BACKGROUND: Porokeratosis is characterised by one or more atrophic patches surrounded by a distinctive peripheral keratotic ridge, typically found on sun-exposed areas, with several clinical variants and typical histological findings. Despite ultraviolet radiation, varies antibody - related autoimmune disease treated with systemic steroids and other immunosuppressive conditions such as chronic liver disease, HIV and organ transplantations have been implicated in its etiopathology. CASE REPORT: We present a case of porokeratosis, associated with idiopathic thrombocytopenia in 74 - year old, otherwise healthy male patient, as we discuss the previously reported associated disorders. CONCLUSION: Regarding all of the polymorphism of clinical presentation, associated disorders and treatment responses, we could conclude that disseminated porokeratosis is still an unknown well disorder, which will continue to surprise the physicians in future. The screening and follow up of the patients is mandatory in all cases because as we see, porokeratosis has multiple unexpected faces, which require circumstantial clinical and paraclinical behaviour.
