Cystic lymphangioma of the stomach with marked reactive changes: a rare cause of gastric outlet obstruction in adult.

Cystic lymphangiomas are benign lymphatic tumours which usually affect the paediatric population and are predominantly located in the head and neck region. Its occurrence during adulthood and an intra-abdominal location are both extremely uncommon. Clinically and radiologically, these lesions often mimic malignancy. Infrequently, these tumours can undergo degenerative and reactive changes obscuring the diagnostic features. We describe hereby an anecdote of cystic lymphangioma with marked reactive changes presenting with the features of gastric outlet obstruction in an adult patient.
