Pityriasis Rosea (PR) is a self-limiting dermatitis lasting from 4 to 7 weeks. PR is classified under Papulo squamous group of skin lesions which have certain common clinical presentations and lead to confusion in diagnosis. We undertook this study to analyze the histomorphological findings of Pityriasis Rosea, and to compare the clinical and histopathological findings with other similar studies. Biopsy of clinically diagnosed/suspected cases of PR lesions were performed in the department of dermatology and sent to the department of pathology in 10% formalin. The specimen obtained was subjected for tissue processing after fixation. Tissue sections are prepared from paraffin block and stained with haematoxylin and eosin, followed by microscopic examination. Pityriasis Rosea is a comparatively rare clinical condition in this group of diseases. A total of 5 cases were studied. Lesions were common in younger age group. Both males and females are affected. Often there is an overlap in morphology and distribution of these lesions clinically, leading to difficulty in diagnosis. Distinct histopathological features and clinical correlation gives a conclusive diagnosis. Specific histomorphological diagnosis is important to distinguish these lesions from other lesions with similar presentations as the treatment and prognosis varies significantly.
