ABSTRACT
Lingual thyroid is an abnormal mass of ectopic thyroid tissue seen in base of tongue caused due to embryological aberrancy in development of thyroid gland. Most of the ectopic tissue is seen in the tongue. Their identification and proper management is essential since they may be the only functioning thyroid tissue occurring in the body. We report a case of lingual thyroid in a 40 year old female patient who was hypothyroid with posterior swelling of tongue. Tc-99 scintigraphy confirmed the clinical diagnosis and surgical excision of entire tissue was done by midline mandibular split osteotomy and patient was placed under lifelong thyroxine replacement. Follow up showed excellent results with minimum patient discomfort.
ABSTRACT
Lipomas are rare in oral and maxillofacial regions although they are the most common tumours of mesenchymal origin in human body. The etiology remains unclear. Various different theories explain the pathogenesis of this adipose tissue tumour and also different histological variants of oral lipoma have been given in literature. A case of intraoral lipoma occurring in mental region in a 77-year-old male is reported along with review of the literature. Wide surgical excision was performed and two-year followup showed excellent healing without any recurrence. Lipomas are benign soft tissue neoplasm of mature adipose tissue seen as a common entity in the head and neck region. Intraoral lipomas are a rare entity which may be noticed only during routine dental examinations. Most of them rarely cause pain, resulting in delay to seek treatment. It is mandatory for a clinician to diagnose intraoral lipomas using latest diagnostic methods and conservatively treat them without causing much discomfort.
