ABSTRACT
INTRODUCTION: Leprosy is a chronic infectious disease caused by M. leprae, which presents in different clinico-pathological forms, depending upon the immune status of the host. Clinical classification gives recognition only to gross appearances of the lesions, whereas the parameters used for the histopathological classification are well defined, precise, and also take into account the immunological features. RESULTS: Of the 182 suspected cases of leprosy which were biopsied, the clinical diagnosis was TT in 32 (17.5%), BT in 70 (38.4%), BB in 5(2.7%), BL in 24 (13.1%), LL in 23 (12.6%), and indeterminate in 28 (15.3%) cases. Of the 182 cases, which were biopsied, only 136 (74.7%) showed histological features consistent with any one type of leprosy. The overall clinicohistological correlation was 74.7 percent. A comparison of the histopathological pattern with that of clinical pattern revealed that the maximum correlation was seen with LL (84.2%), followed by BL (73.3%), BT (64.1%), TT (56%), BB, and IL (50%). CONCLUSION: Because there is some degree of overlap in different types of leprosy, especially the unstable forms, the correlation can be made more accurate by combining clinical and histopathological features.

Gorlin syndrome, also known as Basal Cell Nevus Syndrome (BCNS), is a rare autosomal dominant disorder with complete penetrance and variable expressivity. This syndrome is characterized by developmental anomalies, such as odentogenic keratocysts of the mandible and postnatal tumors, especially multiple basal cell carcinomas (BCCs). The prevalence of this syndrome is variously estimated to be 1 in 60,000 to 1 in 120,000 persons. Mutation in a tumor suppressor, the PTCH1 gene residing on long arm of Ch 9, is responsible for the development of many postnatal tumors. Patients with Gorlin syndrome show multiple abnormalities, none of which is unique to this condition. Our case had almost all the features of this rare syndrome.

The role of histopathology in the diagnosis of donovanosis was assessed in 42 patients. There was heavy infiltration of the dermis with plasma and mononuclear cells but with few lymphocytes and neutrophils. The epidermis contained focal collections of polymorphoneuclear leucocytes. Endothelial proliferation and dilation of dermal blood vessels was striking. Intracellular and extracellular Donovan bodies were shown in Giemsa stained sections from 40 patients. Pseudoepitheliomatous hyperplasia was found in biopsy specimens from a few patients.
