Ectopic thymus tissue

MedGen UID:
869369
Concept ID:
C4023795
Finding
Synonym: Abnormal thymus position
 
HPO: HP:0010517

Definition

The presence of ectopic thymus tissue. Normally, cells of the ventral bud of the third pharyngeal pouch detach and migrate in the eighth gestational week caudally and medially towards the location of the mature thyroid. They migrate further retrosternally into the superior mediastinum. There are two main ways ectopic thymus tissue can develop. Either cells detach along the descensus path and proliferate, thereby forming accessory thymus tissue, or the entire gland fails to descend. [from HPO]

Branchiooculofacial syndrome
MedGen UID:
91261
Concept ID:
C0376524
Disease or Syndrome
The branchiooculofacial syndrome (BOFS) is characterized by: branchial (cervical or infra- or supra-auricular) skin defects that range from barely perceptible thin skin or hair patch to erythematous "hemangiomatous" lesions to large weeping erosions; ocular anomalies that can include microphthalmia, anophthalmia, coloboma, and nasolacrimal duct stenosis/atresia; and facial anomalies that can include ocular hypertelorism or telecanthus, broad nasal tip, upslanted palpebral fissures, cleft lip or prominent philtral pillars that give the appearance of a repaired cleft lip (formerly called "pseudocleft lip") with or without cleft palate, upper lip pits, and lower facial weakness (asymmetric crying face or partial 7th cranial nerve weakness). Malformed and prominent pinnae and hearing loss from inner ear and/or petrous bone anomalies are common. Intellect is usually normal.
