Dysaesthetic penoscrotodynia may be a somatoform disorder: results from a two-centre retrospective case series.

BACKGROUND: Dysaesthetic penoscrotodynia (DPSD) is a poorly understood disorder, in which men experience distressing symptoms such as burning pain in their genital skin. Drugs for neuropathic pain are often used, but with little success. AIM: To review a series of patients with DPSD to highlight common themes and response to treatment. METHODS: Ten consecutive patients with DPSD were identified from specialist male genital dermatology and psychodermatology clinics at two centres. Clinical details, including psychiatric history, were reviewed retrospectively. Patients with no previously diagnosed psychiatric illness completed either the Generalized Anxiety Disorder (GAD)-7 scale and the Patient Health Questionnaire (PHQ)-9 depression scale, or the Hospital Anxiety and Depression Scale (HADS) and the Dermatology Life Quality Index (DLQI). RESULTS: Of the 10 patients, 9 had known or newly diagnosed psychopathology. All patients were offered psychodermatological treatment, of which 7 of 10 accepted. All of those who accepted psychodermatological treatment experienced an improvement in their genital symptoms. When post-treatment scores were collected, improvement in psychiatric symptoms accompanied improvement in genital symptoms. CONCLUSIONS: Psychopathology is almost invariably present in individuals with DPSD, yet these patients rarely volunteer such information. DPSD is most likely to constitute a functional somatic symptom disorder, hence psychodermatological treatment is indicated for its management. This concept reflects a significant change in the approach to this condition.

Tertiary syphilis and Kaposi sarcoma mistaken for systemic sarcoidosis in an HIV-negative patient.

We describe a case of an HIV-negative man who was mistakenly diagnosed as having systemic sarcoidosis, which led to a delay in diagnosing tertiary syphilis and Kaposi sarcoma (KS). The patient presented initially with scrotal swelling and leg oedema. Initial blood tests were unremarkable and HIV testing was negative. The patient then developed unilateral limb weakness. Computed tomography showed lung lesions and hilar lymphadenopathy, while magnetic resonance imaging showed an increased signal in the cervical cord. Serum angiotensin-converting enzyme was raised, and a diagnosis of sarcoidosis was made and the patient started on steroids. Subsequently, his clinical symptoms and radiological abnormalities improved. However, he then developed progressive neurological deficits over several weeks, together with uveitis and cutaneous lesions. A uveitis screen showed a raised venereal disease research laboratory test titre and the cause of his multisystemic symptoms was revisited. He was diagnosed with tertiary syphilis and treated with antibiotics. Dermatologists reviewed the skin lesions and diagnosed KS, which was confirmed with biopsies. The patient's neurological deficit remains. Syphilis should be considered in the differential diagnosis of any patient presenting with neurological problems, skin lesions or symptoms affecting multiple systems. Co-existing KS presented an extra therapeutic challenge in this case.
