Final answer:
Lymphedema in a patient with a lymphatic system malformation is named simply lymphedema. It involves swelling of tissues due to fluid accumulation. The condition that leads to bubbly formation in lymphatic infections is lymphadenitis.
Step-by-step explanation:
If a patient with a malformation of the lymphatic system develops lymphedema, the condition is often caused by the accumulation of lymph fluid that leaks out of capillaries into spaces between cells due to impaired drainage within the lymphatic system. This condition is the result of excess water accumulation in the tissues and is most prevalent in the soft tissues of the extremities. Lymphedema can lead to symptoms such as swelling of the subcutaneous tissues, increased limb size, and tight, stretched skin.
However, when this condition results from a specific cause like an infection such as lymphogranuloma venereum, caused by certain serovars of C. trachomatis, it not only leads to lymphedema but also to the formation of buboes, which are enlarged lymph nodes that can burst and release pus. In the context of your options, the condition that results in the formation of a bubo is B. lymphadenitis.
