Introduction and Importance: Cystic Lymphangiomas (CLs) are rare vascular anomalies of benign nature. The etiology remains a subject of controversy, but they are considered to arise due to anomalies that occur during the normal embryogenic developmental process of lymphatic vessels. They have an estimated incidence rate of merely 1 in every 20,000–250,000 individuals. Since they are mainly known as a disease of the pediatric population, accurate epidemiological rates of CLs, especially in adults, are still unidentified due to the scarcity of published data. Documentation is pivotal to collect further information about them to establish timely diagnoses and minimize the potentially high patient morbidity. Case Presentation: The authors hereby demonstrate the case of a 46-year-old lady who presented to the outpatient general surgery clinic at our university hospital complaining of chronic right hypochondriac abdominal pain. Investigative radiological imaging marked a cystic formation with well-defined borders and homogenous content extending from the lower pole of the right kidney to the lower hepatic border. Clinical Discussion: Surgical intervention was performed by completely resecting the lesion in question. Directly afterward, histopathological analysis was achieved and established the diagnosis of a CL. Conclusion: CL is a rare neoplasm with ill-defined symptoms and ambiguous clinical presentations. They remain poorly studied due to their rarity and lack of sufficient data in the published literature. This magnifies the importance of clinical awareness and time-efficient surgical intervention. Documenting these cases aids in identifying their subsequent etiological origins, disease-specific risk factors, clinical course, and yields proposals of novel therapeutic approaches.

Introduction and Importance: Any defect in the early phases of the normal complex embryogenic pathway might lead to anatomical anomalies that lead to the formation of ectopic thyroid gland tissue. Overall, ectopic thyroid tissue incidence is one in 300 000, and the rate of malignant transformation among those is merely 1%. However, documented cases of malignant transformation of ectopic thyroid tissue in the tonsils have not yet been – to the best of the knowledge – documented in published literature. Case Presentation: We illustrate the case of a 58-year-old female who was referred to the clinic after she underwent a tonsillectomy due to chronic discomfort and gradual difficulty in swallowing. Documentation of an ectopic primary Papillary Thyroid Carcinoma in one of the patient’s excised tonsils was achieved after thorough histopathological and immunohistochemical analyses took place. Radiological evaluation excluded any metastatic involvement and paved the path toward surgical intervention, which was comprised of a total thyroidectomy. Clinical Discussion: Surgical resection of the patient’s thyroid gland was achieved, and the subsequent histopathological analysis of the specimens revealed nodular hyperplasia with degenerative changes but without evidence of malignant transformation in her thyroid gland. Conclusion: Ectopic primary Papillary Thyroid Carcinoma is an immensely rare occurrence, regardless of population parameters. Its incidence could originate in various anatomical locations, but to the best of the knowledge, its incidence in the tonsils has not been previously documented in published literature. Adequate levels of clinical awareness in this situation could timely alleviate patient complaints and aid in performing optimal life-saving interventions.
