Dermatology · STI: pseudobubo of donovanosis

Sample item

A man with a chronic painless, beefy-red genital ulcer develops a fluctuant swelling in the groin, but the swelling is subcutaneous granulation tissue and not an enlarged node. What is this swelling called?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Pseudobubo

In donovanosis, subcutaneous granulomas in the inguinal region mimic nodes and form a pseudobubo, since the lymph nodes are not actually involved. This distinguishes it from the true suppurative buboes of chancroid and LGV.

Option by option

  • A. Groove sign

    The groove sign is the groove between nodes above and below the inguinal ligament in LGV.

  • B. Pseudobubo (correct)

    Correct. A granulomatous groin mass without nodal involvement is a pseudobubo.

  • C. Esthiomene

    Esthiomene is chronic elephantiasis of the female genitalia after LGV.

  • D. True suppurative bubo

    A true bubo is a suppurative inflamed node, as in chancroid.
