What is a characteristic presentation of adult T-cell lymphoma?

Adult T-cell lymphoma, also known as adult T-cell leukemia/lymphoma (ATLL), typically presents with significant lymphadenopathy, which is the enlargement of lymph nodes. This is due to the proliferation of neoplastic T-cells that infiltrate lymphatic tissues. In patients with adult T-cell lymphoma, enlarged lymph nodes can be found in various regions of the body, including the cervical, axillary, and inguinal areas.

The lymphadenopathy associated with this condition is often accompanied by other systemic symptoms such as fever, weight loss, and night sweats, which can further contribute to the overall clinical picture. The prominence of lymph node enlargement makes it a key characteristic of the disease, helping clinicians in making a diagnosis based on clinical examination and imaging studies.

In contrast, the other choices do not have a direct correlation to adult T-cell lymphoma. A croup cough is typically associated with viral infections in children, cyanosis of the lips suggests respiratory or cardiovascular issues rather than lymphoproliferative disorders, and cuts and scrapes are unrelated to the clinical manifestations of ATLL. Therefore, the characteristic presentation of enlarged lymph nodes is a hallmark feature that aids in identifying adult T-cell lymphoma.
