Background: Melanocytic lesions are common and include both benign and malignant conditions. Benign melanocytic nevus may show varied microscopic features and should be differentiated from malignant lesions. In the present study, we analyse the histopathological pictures of different types of benign melanocytic nevi.Materials and methods: This study was a hospital based retrospective study and all the cases reported as melanocytic nevus in the period from Jan 2014 to June 2018 in the Department of Pathology, Manipal Teaching Hospital were retrieved and analysed in the study.Results: A total of 104 melanocytic lesions including 74 cases of benign melanocytic nevus were reported in the study period. Females were affected more with a female to male ratio of 1.8:1. The age range was 5 to 78 years with mean age of 28 years. Among the female patients, the commonest age group was 21-30 years while among the males; the most affected age group was 11-20. The commonest histopathological subtype was intradermal nevus comprising 73% cases followed by compound nevus.  On analysis of the different sites involved, face, head and neck were found to comprise 92% cases. Epidermal changes including hyperkeratosis, acanthosis were common in intradermal nevus. In most cases, tumor cells were arranged in nests. Melanin pigment was noted in majority of the cases. Secondary changes noted were chronic inflammation, fibrosis and multinucleated giant cells.Conclusion: Benign melanocytic nevus may present in varied age range and show wide spectrum of histological features. All pigmented lesions should be biopsied for its subtypes.

Introduction: Skin tumor incidence has increased over the last several decades. A wide range of tumors are encountered in clinical practice. Accurate identification of skin lesions is vital in ensuring malignancies are not missed and that they are treated early to avoid morbidity and mortality.Materials and Methods: A retrospective cross sectional hospital based study on a series of cases was performed in the Department of Pathology, Patan Academy of Health Sciences, Patan Hospital, Lalitpur, Nepal from April 2011 to March 2016. Data from the histopathology database were analyzed using SPSS version 16.0.Results: During the study period, 410 skin biopsies were received, of which 214 (52.2%) were skin neoplasms. Among them, 175 (81.8%) were benign and 39 (18.2%) were malignant neoplasms. Incidence of keratinocytic tumors was highest followed by soft tissue tumors and melanocytic tumors. Intradermal nevus was the most common benign neoplasm. Among the malignant neoplasms, squamous cell carcinoma was most prevalent (46.1%) followed by basal cell carcinoma (15.3%). Skin neoplasms were present in all age groups with maximum number of benign neoplasms prevalent in 21-30 years and malignant in 51-60 years age group. Mean age was 38 years and 58 years for benign and malignant neoplasms respectively.Conclusions: Histopathological evaluation of skin biopsy is an important tool in diagnosis of skin neoplasms. Intradermal nevus and squamous cell carcinoma was the most common benign and malignant neoplasm respectively. Malignant neoplasms were more common in older patients.

Consensus Diagnosis

Background: The histology of melanocytic nevi removed from older patients often differs from that of nevi from younger adults. According to the literature, the most common nevus in older individuals is the intradermal nevus, and purely junctional nevi are rare and should alert the pathologist to a possible melanoma precursor. Objective: To evaluate the histologic features of melanocytic nevi removed from patients > 60 year of age. Methods: Biopsies of nevi ( N = 215) from 172 patients > 60 years (mean age 69 ± 7 years) were examined retrospectively by three dermatopathologists, a consensus diagnosis was rendered, and the spectrum of histologic features was documented. Results: Junctional melanocytic nevi were frequently diagnosed in older patients (21% of cases) and a lentiginous, often heavily pigmented growth pattern was common (12% of nevi). Severely atypical (dysplastic) changes were found in 6% of nevi removed from older patients. Conclusions: We conclude that benign junctional nevi are relatively common in older patients and that a lentiginous, heavily pigmented growth pattern, traditionally associated with younger individuals, is often seen in both junctional and compound nevi in this older age group. This pattern must be differentiated from dysplastic nevus and melanoma in situ, which they may clinically resemble.
