Eritema indurado de Bazin-vasculitis nodular / Erythema induratum of Bazin-nodular vasculitis

Comunicamos un caso de eritema indurado de Bazin-vasculitis nodular en una mujer de 22 años, con una reacción fuertemente positiva al test de la tuberculina, lesiones ulceradas y una buena respuesta a la terapia anti tuberculosa hasta el momento. Se discute la ubicación nosológica de esta entidad y se enfatiza sobre la necesidad de una biopsia amplia adecuada.

A 22-old woman with an erythema induratum de Bazin-nodular vasculitis was reported, the tuberculin test was strongly positive measuring 17 mm of diameter. The patient had indolent ulcerated lesions, the therapy with four anti-tuberculous drugs results effective until now. The existence of the entity as unique or not as well the need of a wide biopsy is discussed.

Secondary Syphilis with Nodular Vasculitis Mimicking Behcet's Disease / 감염과화학요법

Although, erythema nodosum is a common skin manifestation associated with syphilis, nodular vasculitis is a rare feature. Here, we describe a case of a 22-year-old, human immunedeficiency virus negative, non-immunocompromised man who developed recurrent oral and scrotal ulcers with nodular lesions of the lower extremitie. Behcet's disease was initially suspected, however, his serologic test for syphilis was positive, and he was thus diagnosed with secondary syphilis, with a skin biopsy showing nodular vasculitis. The patient was treated with benzathine penicillin, and the skin lesions disappeared after treatment.

Erythema Nodosum: Clinicopathologic Correlations and Their Use in Differential Diagnosis

PURPOSE: Typically, a diagnosis of erythema nodosum (EN) is based on clinical features. However, other diseases manifest with inflammatory nodules of the lower limbs in addition to EN, such as the EN-like lesions of Behcet's disease (BD). The purpose of this retrospective study was to investigate the frequency of histologically proven EN among diseases diagnosed clinically as EN, to determine underlying causes of EN, and to compare clinical and histologic features between EN and other diseases. PATIENTS AND METHODS: We selected 99 patients diagnosed clinically with EN and performed skin biopsies. All pathologic slides were evaluated and diagnosed; and after histologic diagnoses were made we reviewed the patients' medical records. RESULTS: Among the 99 patients diagnosed clinically with EN, 47 were biopsy-verified EN. The EN-like lesions of BD and nodular vasculitis were both in the primary differential diagnosis of EN. No definite difference in clinical features exists among these three diseases. Histologically, EN demonstrated septal panniculitis in the majority of patients. Lobular panniculitis was frequently observed in NV, and mixed or mostly lobular panniculitis was observed in the EN-like lesion. Vasculitis was rarely observed in EN; however lymphocytic vasculitis was observed frequently in EN-like lesions and neutrophilic vasculitis was observed in NV. The frequency of granulomatous inflammation was highest in NV. Some cases of patients with typical BD demonstrated classic EN lesions. CONSLUSION: It was extremely difficult to clinically differentiate EN from EN-like lesions or NV. We feel skin biopsy is mandatory for the diagnosis of lower extremity erythematous nodular lesions.
