INTRODUCTION: Isolated Thymic cysts are very uncommon lesions and are believed to account for approximately 3% of all anterior mediastinal masses (1). Thymus is derived from 3 rd pharyngeal pouches with only a small contribution from 4 th pharyngeal pouches. CASE REPORT: An upper lateral neck swelling on the left side of short duration which was diagnosed pre-operatively as, branchial cyst, in a 7 year female child. There were no symptoms of pain or obstruction. Excision biopsy was done and the histopathological diagnosis was confirmed as Thymic cyst. Embryological and histological aspect with review of literature has been done.
Cervical thymic cysts: CT appearance of two cases including a persistent thymopharyngeal duct cyst
Pediatric Radiology, 1995
Cervical thymic cyst is a rare entity of either congenital or inflammatory origin described infrequently in literature. The asymptomatic nature of the entity and the rarity of the lesion frequently lead to a diagnostic dilemma many times. We present a case of cervical thymic cyst that presented to us as an asymptomatic neck mass that was managed surgically. Cervical thymic cyst should be kept as a differential diagnosis of an asymptomatic neck swelling especially in children.
A Case Report of Mediastinal Thymic Cyst
Journal of Babol University of Medical Sciences, 2016
BACKGROUND AND OBJECTIVE: Incidence of thymic lesions in the form of mediastinal cyst is very rare and is accompanied by risk of malignancy, which may induce signs of compression in mediastinum or accidentally be found during imaging. A case of mediastinal thymic cyst with compression-induced shortness of breath is presented. CASE REPORT: A 40 year old woman underwent diagnostic assessment because of shortness of breath. Considering imaging results regarding upper mediastinal cystic lesion with possible origin of thymus, she underwent excision of mass and middle sternum. Histopathologic examination reported a simple thymic cyst. CONCLUSION: Considering respiratory problems of patients with mediastinal cystic lesion, timely diagnosis and treatment is necessary to prevent probable malignancy in addition to relieving symptoms.
Symptomatic Cervical Thymic Cyst: A Case Report and Literature Review
Journal of Comprehensive Pediatrics, 2013
Introduction: Ectopic cervical thymic cyst is a very rare cause of neck masses in children. The diagnosis is sometimes very difficult and preoperative, correctly diagnosed thymic cysts in the neck are very low. Case Presentation: We report a 5-year-old boy with a left sided cervical mass and respiratory distress following a common cold, and ultrasound and CT scan revealed a cystic mass in the left neck with extension to the anterior mediastinum, suggesting cystic hygroma. After complete resection of the cyst and its extension, pathology report demonstrated simple thymus cyst. Discussion: Thymic cyst must be considered in differential diagnosis of a young child with a cervical mass.
Thyroglossal Duct Cyst in a 3-Month-Old Infant: A Rare Case
Turk Otolarengoloji Arsivi/Turkish Archives of Otolaryngology, 2016
Thyroglossal duct cyst (TGDC) is the most common congenital midline neck mass in children. It usually becomes symptomatic following a respiratory tract infection and is usually diagnosed at 5 years of age. Thyroglossal duct cyst is rarely observed in less than 1-year-old infants. In this study, we present a 3-month-old infant with TGDC, who was administered multiple courses of antibiotic therapy for the hyperemic, draining, midline neck mass that had existed since he was 15 days old. Physical examination revealed an infrahyoid midline neck mass measuring 3×3 cm, which moved while swallowing and had a sinus opening in the overlying skin. The patient underwent Sistrunk operation under general anesthesia. Histopathologic examination revealed TGDC. One-year follow-up revealed no recurrence.
Cervical Thymic Cyst - An Overlooked Entity
Malaysian Journal of Paediatrics and Child Health
Thymic cysts are one of the rare causes of neck masses in the paediatric age group. Patients may complain of neck swelling either central or lateral neck swelling. There is difficulty in diagnosing a cervical thymic cyst as it may mimic a branchial cleft cyst or a cervical lymphangioma. Definitive diagnosis of a thymic cyst requires histopathological examination of thymic tissue. We report a case of a 6-year-old girl who presented with painless lateral neck swelling for 2 months duration. Computed tomography (CT) scan showed a left branchial cyst with retropharyngeal extension. The patient underwent complete excision of the mass and histological examination was reported as a cervical thymic cyst. Postoperatively, she was able to be discharged after serial follow-ups with no signs and symptoms of recurrence.

Kierownik: prof. dr hab. M. A. Karolczak The Authors of this study present a case of a 13-month old child subjected to surgical intervention for a cervical thymic cyst. The origin of lesions in children is usually associated with remnants from the development of the fetal thymus gland. When the tumor attains significant size, especially in the presence of clinical symptoms, such as respiratory disturbances and problems with feeding, surgical management is required. In spite of the rarity of thymic cysts, it should be considered in cases of differential diagnosis for neck tumors in children. Proper diagnosis is usually possible after the histopathological evaluation of removed tissues. The cervical approach enables removal of the entire lesion, even if partially localized in the thoracic cavity.

Thymic cysts are considered uncommon lesions in the differential diagnosis of pediatric neck masses. They usually present in the 1st decade after the age of 2 years, possibly because the thymus attains its greatest development before puberty. They may be found anywhere along the normal descent route of the thymus gland from the mandible to the sternal notch; 50% extend into the mediastinum. Most patients are asymptomatic, although respiratory complications may occur. A review of the operative records in our hospital over the last 10 years revealed two cases of cervical thymic cysts (CTC) in a 5-and a 9-year-old boy. Both children presented with an atraumatic, painless, enlarging mass in the left side of the neck anterior to the sternocleidomastoid muscle. Neither boy had respiratory problems or swallowing difficulties. Ultrasound and computed tomography showed a lesion consistent with a tentative diagnosis of a branchial cyst in one boy and an extensive cystic hygroma in the other. Both lesions were approached through a transverse cervical incision and, although closely adherent to the internal jugular vein, carotid artery, and vagus nerve, were resected completely. There were no postoperative complications and so far there has been no recurrence. CTCs are uncommon benign lesions that should be considered in the evaluation of neck masses in children. Preoperative diagnosis is unusual and, at this time, there is no preoperative radiologic test that can accurately identify a neck mass as a CTC. Histologic investigation of the excised specimen showing thymic tissue remnants with pathognomonic Hassall's corpuscles and cholesterol clefts in the cyst wall is the only definitive diagnosis. Evolution is benign. Intact, complete surgical excision remains the treatment of choice.
