Introduction and Aim: Most of the lesions affecting pinna are cutaneous conditions. Those arising from the cartilage are extremely rare, whereas those from the soft tissue like vascular, stromal and adnexal components are relatively common. The present study aims at analysing the proportion, types, and categories of lesions affecting the pinna. Methods: Following institutional ethics committee approval, a retrospective analysis of medical records of 40 patients who underwent surgical excision of pinna lesions from 2006 to 2018 was conducted at a tertiary care hospital in Dakshina Kannada, India. Lesions were grouped as benign adnexal, benign soft tissue, malignant lesions, and infection/inflammation. Results: Median age was 47.5 years and mode was 59 years. There were thirty (75%) males and ten (25%) females. The commonest lesions included epidermal cyst (25%), followed by seborrhoeic keratosis (17.5%), and squamous cell carcinoma (10%). Conclusion: A wide spectrum of entities affecting the pinna were encountered in the present study. Superficial cystic lesions are the most frequent type found in pinna and are amenable to simple excision. Benign neoplasms require surgical intervention; malignancy is also to be kept in mind while making a clinical diagnosis, necessitating wide clearance with or without neck dissection. Early intervention and confirmation of diagnosis by histopathological examination helps not only in successful management but also in preventing disfigurement and psychosocial complications.

Cutaneous neurocristic hamartoma is a rare developmental complex melanocytic lesion of neural crest origin in the dermis and subcutis with diverse histological differentiation including melanocytic, neurosustentacular, and mesenchymal elements. Cutis verticis gyrata is a cerebriform thickening of the scalp manifesting as folds, ridges, or creases. We report a case of cutaneous neurocristic hamartoma of the scalp in a 20-year-old woman presenting as cutis verticis gyrata. Microscopically, the lesion involved the dermis and the subcutis. Dendritic pigmented melanocytes were seen in between the collagen bands. Plexiform islands consisting of cords and palisades of spindled cells were also apparent. Immunohistochemically, HMB-45 positivity was observed in the dendritic melanocytic cells. S-100 protein was positive in dendritic melanocytes and in the Schwannian cells. The stromal cells showed CD34 staining. This lesion is presented because of its rarity, unusual clinical appearance, and resemblance to both a neurocristic hamartoma and large plaque type of blue nevus.
