Correct Answer - C
Ans. is c i.e., Develops from jugular lymphatic sequestration


Cystic hygroma
Cystic hygroma is a swelling usually occuring in the lower third of the neck

It is most commonly seen in posterior triangle of the neck, but may also occur in axilla, groin & mediastinum

It results due to sequestration of a portion of the jugular lymph sac
from the lymphatic system.


It usually manifests in the neonate or in early infancy (occasionally
present at birth) The swelling is soft and partially compressible and invariably increases in size when the child coughs or cries.

The characteristic that distinguishes it from all other neck swellings is that it is brilliantly translucent.


...The cysts are filled with clear
lymph and are lined by endothelium.

Mostly these are multiple cysts but occasionally they can be
unilocular.
It may show spontaneous regression.
Treatment [Ref.: Sabiston 18/e p2053; Schwartz 9/e p1415]
There are two methods of

treatment: Surgical excision &
Sclerotherapy

Sabiston writes- "Complete surgical excision is the preferredtreatment; however, this may be impossible because of the hygroma
infiltrating within and around important neurovascular structures.
.
Because hygromas are not neoplastic tumors, radical resection with removal of major blood vessels and nerves is not indicated.


.Injection of sclerosing agents such as bleomycin or the derivative of
Streptococcus pvogenes OK-432 have also been reported to be
effective in the management of cystic hygromas. Intracystic injection of sclerosants appears to be most effective for macrocystic
hygromas, as opposed to the microcystic variety."


"The modern management of most cystic hygromas includes the
combination of surgical excision and image-guided sclerotherapy."-
Schwartz
