Program-wide review and follow-up of erythema Induratum of Bazin and tuberculosis-associated ocular inflammation management in a TB low-incidence setting: need for improved treatment candidate selection, therapy standardization, and care collaboration.

BACKGROUND: Erythema induratum of Bazin (EIB) - nodular vasculitis associated with Mycobacterium tuberculosis (TB) - and Tuberculosis-Associated Ocular Inflammation (TB-AOI) represent uncommon manifestations of TB. There is limited data and a lack of diagnostic and treatment standards for these conditions. METHODS: Eleven-year retrospective review of EIB and TB-AOI cases managed in a provincial TB program with prospective phone-based follow-up of anti-tubercular therapy (ATT) recipients. Presumptive TB-AOI and EIB diagnoses were determined by ophthalmologist or dermatologist assessments correlated with positive tuberculin skin test and/or QuantiFERON-TB Gold, along with pathologic criteria in EIB cases. RESULTS: Of 21 EIB and 20 TB-AOI cases that received ATT, 13 and 11, respectively, were reached for follow-up. The majority of EIB and TB-AOI cases were female and immigrated from TB high-burden countries. Median durations of pre-diagnosis symptoms were 2 and 0.8 years (IQR 2.5 & 1.1) for EIB and TB-AOI cases, respectively. Overall, 14 different ATT regimens were used for a median duration of 6 months (range 5-9). ATT related adverse events resulting in treatment discontinuation occurred in 14% of EIB and 10% of TB-AOI cases. On last follow-up, 76% of EIB and 42% of TB-AOI had improvement or resolution of disease. CONCLUSION: EIB and TB-AOI were uncommon presentations receiving variable therapy. While treatment response was modest for EIB cases, TB-AOI cases had sub-optimal treatment outcomes. The unique diagnostic and management challenges presented by these conditions in TB low-incidence settings highlight a need for improved treatment candidate selection, therapy standardization, and cross-specialty medical collaboration.

Nodular Vasculitis in a Patient With Crohn's Disease on Vedolizumab.

Erythema induratum (EI), or nodular vasculitis (NV), is a type of panniculitis that is often associated with vasculitis affecting various-sized veins, venules, and arteries in reaction to various causative factors. Historically, EI was highly linked to tuberculosis, but in 1946, Montgomery first proposed the term NV to describe cases of EI not associated with tuberculosis. Only 2 reports of NV associated with inflammatory bowel disease have been reported in the literature. The authors report a 60-year-old woman with Crohn's disease presenting with exacerbation of NV in the setting of vedolizumab therapy.

A 4-month-old baby presenting with dermal necrotizing granulomatous giant cell reaction at the injection site of 13-valent pneumococcal conjugate vaccine: a case report.

INTRODUCTION: Adjuvants (for example, aluminum salts) are frequently incorporated in licensed vaccines to enhance the host immune response. Such vaccines include the pneumococcal conjugate, combinations of diphtheria-tetanus/acellular pertussis, tetanus- diphtheria/acellular pertussis, hepatitis B, some Haemophilus influenzae type b, hepatitis A, and human papillomavirus. These preparations have been associated with complicated local adverse events, especially if administered subcutaneously or intradermally in comparison to deep intramuscular injection. We describe a severe inflammatory reaction at the site of an injection of 13-valent pneumococcal conjugate vaccine. CASE PRESENTATION: A 4-month-old Arab baby boy developed dermal necrotizing granulomatous giant cell reaction at the injection site (right anterior thigh) of the second dose of 13-valent pneumococcal conjugate vaccine. Ziehl-Neelsen and periodic-acid Schiff were negative. This reaction probably resulted from improper intramuscular administration because the first (at 2 months of age) and third (at 10 months of age) doses were uneventful. CONCLUSIONS: Dermal necrotizing granulomatous reactions are a serious complication of the 13-valent pneumococcal conjugate vaccine. Health care providers need to administer this preparation deeply into a muscle mass. Completing the vaccine series is an acceptable option. Physicians are encouraged to report their experience with completing vaccine series following adverse events.

Simultaneous occurrence of papulonecrotic tuberculid and erythema induratum in a patient with pulmonary tuberculosis.

Although papulonecrotic tuberculid is an uncommon cutaneous manifestation of tuberculosis (TB) associated with Mycobacterium tuberculosis infection, the simultaneous occurrence of papulonecrotic tuberculid and erythema induratum is even rarer. Papulonecrotic tuberculid occurs predominantly in young adults and is characterized by eruptions of necrotizing papules that heal with varioliform scars. Histopathologic findings include wedge-shaped necrosis of the dermis, poorly formed granulomatous infiltration, and vasculitis. Stainings and culture for acid-fast bacilli from skin biopsies are usually negative for M. tuberculosis, although the eruptions resolve with antitubercular therapy. Few patients with papulonecrotic tuberculid, especially with concurrent occurrence of erythema induratum, have been reported in the English literature. Here we report a case of a 12-year-old girl with simultaneous occurrence of papulonecrotic tuberculid and erythema induratum accompanying pulmonary TB.

Tuberculosis cutánea en una zona de Mallorca (2003-2011) / Cutaneous tuberculosis in an area of Mallorca (2003-2011)

Antecedentes y objetivo. La tuberculosis constituye un importante problema sanitario, también en nuestro medio. Este estudio sepropone describir las características clínicas y epidemiológicas de la tuberculosis cutánea en nuestro medio. Pacientes y métodos. Estudio retrospectivo de los casos de tuberculosis cutánea diagnosticados de enero de 2003 a julio de 2011 en un hospital de Mallorca. Se registraron las formas clínicas, la metodología diagnóstica empleada, el tratamiento utilizado y la evolución clínica. Resultados. Se diagnosticaron 28 casos de tuberculosis con afectación cutánea (5,9% del total de tuberculosis), tuberculosis verdadera en 15 casos (14 escrofulodermas, un empiema necessitatis) y tubercúlides en el resto (8 casos de eritema indurado de Bazin y 5 de eritema nodoso). El foco de origen de los escrofulodermas fue ganglionar (10), óseo (4) y pleural (1); 13/28 pacientes eran originarios de otros continentes. La mayoría de los pacientes fueron tratados con 3-4 fármacos tuberculostáticos, evolucionando favorablemente. Conclusión. La tuberculosis cutánea no es infrecuente en nuestro medio. En las tuberculosis cutáneas verdaderas el cultivo es el método diagnóstico más rentable, mientras que en las tubercúlides generalmente la histología es la que proporciona el diagnóstico(AU)

Background and objective. Tuberculosis is an important health care problem, even in our setting. The objective of this study is to describe clinic and epidemiological features of cutaneous tuberculosis in our area. Patients and methods. A retrospective study was performed of all patients diagnosed of cutaneous tuberculosis in a hospital in Mallorca (Spain) from January 2003 to July 2011. The clinical forms, diagnostic methods used, treatment used and clinical course were recorded. Results. Twenty-eight cases of cutaneous tuberculosis were diagnosed (5.9% of the tuberculosis cases diagnosed in this period), 15 with classic cutaneous tuberculosis (14 scrofuloderma, 1 empyema necessitatis) and 13 patients with tuberculids (8 erythema induratum of Bazin disease and 5 erythema nodosum). Scrofulodermas came from lymph nodes in 10 of the patients, infected bone in 4 and pleural in one case; 13/28 patients came from other continents. Most of the patients were treatment with 3-4 tuberculostatic drugs, with favorable course. Conclusions. Cutaneous tuberculosis is not uncommon in our setting. In classic cutaneous tuberculosis culture is the gold standard diagnostic method while tuberculids are most commonly diagnosed by histology(AU)

Erythema induratum (nodular vasculitis) associated with Crohn's disease: a rare type of metastatic Crohn's disease.

We herein report a patient with erythema induratum/nodular vasculitis (EI/NV) associated with Crohn's disease (CD), which is considered to be a rare type of metastatic CD. A 54-year-old woman, who had a history of CD, presented with erythematous nodules on her legs. The histopathological features of the skin biopsy revealed a granulomatous, mixed septal and lobular panniculitis, which was characterized by many discrete epithelioid cell granulomas (necrobiotic/necrotizing-type and sarcoidal type), necrosis of the adipocytes, and granulomatous phlebitis in the muscular wall of a subcutaneous vein. A review of the pertinent literature and the presented case suggested the following: (1) panniculitis associated with CD may be either an erythema nodosum type or an EI/NV type; (2) so far, the reported cases of metastatic CD or granulomatous vasculitis in CD rarely presented with granulomatous panniculitis without dermal involvement, and most cases showed histopathological features that were similar to or indistinguishable from those of EI/NV; and (3) the finding of granulomatous vasculitis (especially the presence of discrete epithelioid cell granulomas involving the veins or venules) may be a characteristic feature of EI/NV associated with CD, in contrast to the finding of acute vasculitis, which is typically present in patients with EI/NV due to causative factors other than CD.

Erythema induratum of Bazin associated with Addison's disease: first description.

CONTEXT: Erythema induratum of Bazin (EIB) is considered to be a tuberculid reaction and consists of recurrent painful nodules. The differential diagnosis includes diseases like nodular vasculitis, perniosis, polyarteritis nodosa and erythema nodosum. CASE REPORT: We report the case of a woman with EIB who developed Addison's disease during treatment with anti-tuberculosis drugs with good response to glucocorticoid replacement. The diagnosis was obtained through the clinical picture, positive tuberculin test and positive BCG (bacillus Calmette-Guérin) test on the histological sample. Anti-tuberculosis drugs and glucocorticoid replacement led to disappearance of the signs and symptoms. CONCLUSIONS: This is the first description of an association between EIB and Addison's disease. It should be borne in mind that tuberculosis is an important etiological factor for Addison's disease.

Erythema induratum and chronic hepatitis C infection.

Erythema induratum, or nodular vasculitis, was initially described as a type of cutaneous tuberculosis. Currently, it is considered a multifactorial syndrome of lobular panniculitis of unknown cause. An association between erythema induratum and hepatitis C virus (HCV) has been suggested in previous reports. We report the case of a 49-year-old male presenting with a 3-year history of itchy, painful red to violaceous cutaneous nodules and plaques on both legs that had been unresponsive to topical dermatologic treatments. Evaluation of persistent serum transaminase elevations led to a diagnosis of chronic hepatitis C with bridging liver fibrosis. A thorough evaluation to exclude mycobacterial infection was performed, and anti-tuberculosis treatment was started based on a positive QuantiFERON test. There was no improvement in the skin lesions with this treatment. The patient then received standard antiviral therapy with pegylated interferon and ribavirin for 48 weeks. Treatment produced an early virologic response with significant improvement in the skin lesions, pain and pruritus. Six months after antiviral treatment, virologic relapse occurred without recurrence of the cutaneous lesions. There appears to be an association between erythema induratum and hepatitis C infection, probably mediated by circulating immune complexes. Interestingly, lesions improve with antiviral treatment and, as shown in this case, the effect may be sustained after stopping treatment despite virologic relapse.
