PECULIARITIES OF FOLLMANN’S SYPHILITIC BALANOPOSTHITIS DIFFERENTIAL DIAGNOSIS

Abstract

Syphilitic balanitis, or Follmann’s balanoposthitis, is an atypical form of primary syphilis that can mimic various diseases of the male genitourinary system. Prompt diagnosis is crucial to avoid treatment complications. The aim of the study is understanding the peculiarities of the differential diagnosis of Follmann’s syphilitic balanoposthitis. Materials and methods. The clinical presentation of syphilitic balanoposthitis of Follmann varies from erosive lesions to dense infiltration and erythematous spots. Patients complain of painful erosions and swelling of the glans penis, with regional lymphadenitis commonly observed. Differential diagnosis includes excluding other infections, such as herpes, candidiasis, allergic dermatitis, and erythroplasia of Queyrat. Laboratory diagnostics involve direct methods for detecting T. pallidum and serological tests. Treatment involves the use of benzathine benzylpenicillin or alternatives, such as doxycycline, in cases of penicillin allergy. Results. Clinical case was analyzed, features of the course, diagnostic difficulties, and treatment results were determined. Conclusions. Clinical case highlights the importance of thorough examination in detecting infection sources, especially in atypical primary syphilis with Follmann’s balanoposthitis. Due to the possible seronegative phase, a comprehensive differential diagnosis is vital to prevent misdiagnosis. Accurate diagnosis and effective treatment require detailed anamnesis, clinical examination, and appropriate serological and bacteriological tests.
