BACKGROUND Epstein. S in 1942 described PMLE under the name of Prurigo aestivalis. He first hypothesised that PMLE represents a form of delayed-type hypersensitivity response to an endogenous, cutaneous UV-induced antigen, because of the hours or days delay between sun exposure and manifestation of symptoms, and the histological appearance of lesional skin. Firm evidence; however, has been lacking and the responsible allergen has not been identified. PMLE a specific entity encompassing six clinical manifestations: Small erythematous papulovesicles, eczematous lesions, large papules, oedematous plaques, prurigo nodules and erythema multiforme-like lesions. The histological features of PMLE are characteristic, but not pathognomonic and vary with the different clinical presentation. A sincere effort has been put in this study to understand the clinical and histopathological features of polymorphic light lesions. The study is intended to help the practising physicians and dermatologists to diagnose the pathology on time and intervene before it develops into complications. METHODS Material for the present study consisted of 100 cases of clinically diagnosed untreated cases of polymorphous light eruption, who were attending the skin and STD and Leprosy Department, Kakatiya Medical College, Warangal, during January 2014 to Dec 2014 were selected for this study. The patients were selected randomly irrespective of age, sex, socioeconomic status. RESULTS Histopathology showed perivascular lymphocytic infiltration in the dermis in majority of our cases (93.33%) and clinicohistopathological correlation was observed in most cases; hence apart from clinical examination, histopathological examination plays an important role in diagnosing PMLE. CONCLUSION 56 percent of the patients complained pruritus followed by burning. The study was similar to other studies in comparison.

BACKGROUND Skin changes of diabetes mellitus (DM) appear subsequent to the progression of the disease, they can be the sign that appear first in some cases and in others they may present years after the primary disease. AIMS To study the skin manifestations in diabetic patients and to know the incidence of skin manifestations of diabetes mellitus. MATERIAL AND METHODS This study was undertaken at our hospital, MGM Hospital, Warangal, Telangana for a period of one year from 1 st January 2013 to 31 st December 2013. 100 established cases of Type 2 diabetic patients (50 males and 50 females) both in-patients as well as outpatients were enrolled for the study. RESULTS Dermatological manifestations were seen in 64% of the diabetes patients. Most common was dry skin, followed by infections and acanthosis nigricans in diabetics. Complications of the disease were observed to a tune of 30% in diabetic cases. CONCLUSION Skin manifestations are more common in diabetic patients and should be sought for.
