Multiple endocrine neoplasia type 2B (MEN2B) syndrome is a rare genetic disorder primarily driven by mutations in the RET proto-oncogene. MEN2B exhibits diverse symptoms affecting multiple organ systems, with mucosal neuromas being a prominent feature. These benign tumors contribute to the syndrome's clinical variability, alongside medullary thyroid carcinoma and pheochromocytoma. The article presents a case study of a young girl diagnosed with MEN2B, complicated by laryngeal neuromas leading to respiratory distress post-thyroidectomy. Laryngeal neuromas are exceedingly rare, underscoring the importance of recognizing such manifestations for proper airway management, especially during surgical interventions. Despite its rarity, MEN2B presents significant clinical challenges, requiring early detection, genetic counseling, and multidisciplinary management for improved outcomes. Clinicians must remain vigilant for rare manifestations like laryngeal neuromas to prevent serious complications, particularly during surgical procedures., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Intramuscular lipomas, typically found in subcutaneous tissue, rarely affect deeper muscular planes, especially those of the head and neck region. The following are 3 cases of intramuscular lipomas involving the sternocleidomastoid muscle. The first 2 patients presented with painless, palpable masses confirmed by diagnostic imaging as well-circumscribed intramuscular lipomas. One was treated surgically, while the other was managed conservatively with monitoring and close follow-up. The third patient reported dysphagia associated with occasional dyspnea and mild pain. The mass was identified as infiltrative lipoma and was resected surgically. Complete tumor removal with no recurrence at 6 months was observed for the first and last cases. The second case was serially followed at 3 and 6 months with no interval changes. We report the largest case series on intramuscular lipomas of the sternocleidomastoid muscle to enhance our understanding of this rare entity., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)
