RESUMO
The head and neck regions are rather uncommon for dermoid cysts. Dermoid cysts are among the rarest types of oral cysts, accounting for a very small proportion of cases in the oral cavity. They are thought to be caused by defective development along the embryonic lines of fusion, involving both ectodermal and endodermal elements. This case study details a 16-year-old girl who complained of a smooth, globular swelling that had been present for two months over the floor of the mouth and extending to her left submandibular region. Following ultrasonography (USG) confirmation, the patient underwent a full surgical excision, and the histological report revealed a sublingual dermoid cyst.
RESUMO
Melanoma is a malignant neoplasm of melanoblasts, which are the precursors of the melanocytes arising from the neural crest cells. Melanomas can occur at various sites like the skin, eyes, upper esophagus, and meninges due to the migration of neural crest cells. Usually, the prognostic factors are decided based on the Breslow index. This case report describes a 61-year-old female who presented with the complaint of pinkish irregular swelling over the left side of her face for six months. The patient had a surgical resection, and the condition was determined to be invasive melanoma following confirmation by magnetic resonance imaging (MRI) and histological examination. Through our case report, we aim to shed light on the existing protocol for managing malignant melanoma while also exploring new aspects of presentation and multidisciplinary action.
