Absceso frío tuberculoso. Revisión de la literatura a propósito de cinco casos en Angola / Tuberculous cold abscess. Literature review on five cases in Angola

RESUMEN Introducción: El absceso frío tuberculoso es la forma clínica más frecuente de tuberculosis cutánea. Objetivo: Familiarizar a los médicos generales con las características clínicas del absceso tuberculoso frío para asegurar su diagnóstico y tratamiento específico en la consulta de Cirugía del Hospital General N'gola Kimbanda en Namibe, Angola en 2018. Método: Se revisó la literatura sobre el tema en bases de datos científicas como Medline, PubMed, SciELO, Scopus, Clinical Key, LILACS con los descriptores: tuberculosis extrapulmonar y absceso frío tuberculoso. Resultados: Los pacientes, tres varones y dos hembras, tres adultos y dos infantes, todos desnutridos, con antecedentes de tuberculosis pulmonar y mal de Pott que fueron enviados a consulta con el diagnóstico de lipoma. En todos los casos se diagnosticó absceso frío tuberculoso, 3 de localización lumbar, 1 toracolumbar y 1 lumbosacra confirmados por microbiología y tratados según los protocolos de las especialidades de Cirugía y Neumología. Conclusiones: Es necesario que los estudiantes de Medicina, médicos generales y especialistas que en su desempeño enfrentan a dichos pacientes dentro y fuera de Cuba se empoderen de las características semiológicas del, también llamado, goma tuberculoso, a fin de identificarlo en los pacientes de riesgo y garantizar su tratamiento médico-quirúrgico específico para evitar la discapacidad y mortalidad asociada a esta temida infección que sigue constituyendo un azote social.

ABSTRACT Introduction: Tuberculous cold abscess is the most common clinical form of skin tuberculosis. Objective: To familiarize general physicians with the clinical characteristics of tuberculous cold abscesses to ensure their diagnosis and specific treatment at the Surgery Department of the N'gola Kimbanda General Hospital in Namibe, Angola in 2018. Method: Literature on the subject was reviewed in scientific databases such as Medline, PubMed, SciELO, Scopus, Clinical Key and LILACS with the following descriptors: extrapulmonary tuberculosis and tuberculous cold abscess. Results: The patients, three males and two females, three adults and two infants, all of them malnourished, with a history of pulmonary tuberculosis and Pott's Disease, who were sent for consultation with a diagnosis of lipoma. In all cases, tuberculous cold abscesses were diagnosed, 3 of them in lumbar location, 1 in thoracolumbar and 1 in lumbosacral locations, confirmed by microbiology and treated according to the protocols of the specialties of Surgery and Pneumology. Conclusions: It is necessary that students of Medicine, general physicians and specialists who face these patients inside and outside of Cuba to gain in knowledge with the semiological characteristics of the tuberculous cold abscess, also known as tuberculous gum, in order to identify it in the patients in risk groups, and to guarantee their specific medical-surgical treatment to avoid the disability and mortality associated to this infection that still constitutes a major issue.

Scrotal skin nodule: sebaceous cyst or tuberculosis? A lesson learnt!

Tuberculosis (TB) is a great mimic of many diseases and may present a dilemma in diagnosis. Sebaceous cyst is the commonest swelling that occurs in the scrotal skin. We present a 23-year-old patient who presented with a painful hard scrotal skin nodule, clinically diagnosed to be an infected calcified sebaceous cyst, excised and reported to be due to TB. Nodular scrotal skin TB is extremely rare but should nonetheless be considered as a differential diagnosis in regions where it is prevalent. Thus, excision of any suspicious nodule is indicated.

Cutaneous and articular tuberculosis in a renal transplant recipient.

Seven months after undergoing kidney transplantation, a 56-year-old woman presented with papules and ulcers in her right forearm. The patient received antibiotics for 8 months with limited improvement. Eleven months after symptom onset, she presented with acute arthritis in her left knee. Asynovial fluid culture yielded Mycobacterium tuberculosis, and a forearm ulcer biopsy showed granulomatous inflammation. After surgical fistulectomy and 12 months of tuberculosis treatment, she was cured. Chronic cutaneous ulcers and articular manifestations in TB are rare, but they should always be considered in the differential diagnosis for immunosuppressed patients. Surgical intervention and prolonged treatment might be necessary.

Cutaneous and articular tuberculosis in a renal transplant recipient

Abstract Seven months after undergoing kidney transplantation, a 56-year-old woman presented with papules and ulcers in her right forearm. The patient received antibiotics for 8 months with limited improvement. Eleven months after symptom onset, she presented with acute arthritis in her left knee. Asynovial fluid culture yielded Mycobacterium tuberculosis, and a forearm ulcer biopsy showed granulomatous inflammation. After surgical fistulectomy and 12 months of tuberculosis treatment, she was cured. Chronic cutaneous ulcers and articular manifestations in TB are rare, but they should always be considered in the differential diagnosis for immunosuppressed patients. Surgical intervention and prolonged treatment might be necessary.

An immunocompetent young patient with tuberculosis of the penis: a challenging case.

Tuberculous chancre is an extremely rare form of cutaneous tuberculosis. The genital area is a possible site of presentation. We present a case of a young male with a persistent balanopreputial ulceration resembling a luetic chancre with negative serology for syphilis. The diagnosis was based on the specific pathologic features and the positive intradermal reaction to tuberculin. A successful treatment was achieved by combining antituberculosis treatment and surgical approach with circumcision. After six months of antituberculosis treatment, the patient developed paradoxical inguinal lymph node enlargement, which, after surgical excision and biopsy, was not followed by a relapse of the disease and needed no further therapy. Tuberculosis should be considered a potential diagnosis in the case of a persistent genital ulcer.

Tuberculous botryomycosis of the hand: case report.

We report a case of a 17-year-old boy who presented with botryoid lesions of both hands. These lesions resembled those of cutaneous botryomycosis. We treated him with surgical debridement and were unable to isolate infective agents initially. However, 3 months later Mycobacterium tuberculosis grew in the culture. One year of antituberculous drug therapy resulted in healing of the lesions.

Tuberculosis verrucosa cutis in a patient with keloid over ear lobule.

Tuberculosis (TB) is a global health problem with predominance in resource-poor countries. Extrapulmonary TB constitutes approximately 10% of the cases and can present as different forms depending on the route of entry. Cutaneous TB is a small subset of the extrapulmonary TB. Cutaneous TB can either be of primary origin or secondary origin or it can be a part of a systemic infection. TB verrucosa cutis (TBVC) is the exogenous reinfection of TB in a previously sensitised patient. Routine cultures do not have a high yield in TBVC due to the paucibacillary nature of the organism. Here we are presenting a rare case of a patient who developed in a keloid over the right ear lobule following ear piercing. This has only been presented once in the previous literature and for the first time in the head and neck region.

Non-healing sinus on the back: a rare presentation of genitourinary tuberculosis.

A case is reported of renal tuberculosis presenting as a non-healing sinus in the renal area. This presentation of renal tuberculosis is very rare, especially in the pediatric age group.

Long-term course and treatment of a cutaneous BCG infection.

The authors report and discuss a rare case of the long-term course and treatment of cutaneous BCG infection in an HIV-negative, healthy nurse. Over 5 years we cured the wrist and lower leg cutaneous tuberculosis infection caused by an accident at work. Persistent antituberculous therapy and surgical procedure were applied, but after detection of an encapsulated abscess in the wrist followed by needle aspiration, antituberculous therapy was sufficient and our patient was cured. Failing the addition of local applications, antituberculous therapy with radical surgical treatment remains the recommended treatment in cutaneous infections.

[Scrofuloderma with osteoarticular tuberculosis in the Ferrol health district]. / Escrofulodermia con tuberculosis osteoarticular en el área sanitaria de Ferrol.

INTRODUCTION: Scrofuloderma results from direct extension of an underlying tuberculous focus such as bone, joint or even the epididymis to the overlying skin, but is more frequent over a lymph node, mainly in the cervical region. METHODS: We analysed all cases of scrofuloderma with a bone or joint focus evaluated in the sanitary area of Ferrol, with a current population of 220,000, during a 15-year period. We describe the clinical, histopathological, and microbiological data of patients. RESULTS: We found 6 cases of scrofuloderma with osteoarticular tuberculosis. This series includes five men and one woman, aged 37 to 80. Visceral involvement was found in 3 patients (50 %). CONCLUSION: Osteoarticular tuberculosis comprises 10 % of all extrapulmonary tuberculous infections. There is a high probability of visceral involvement in patients with scrofuloderma. Underlying bone involvement should be rule out in all patients with scrofuloderma, especially in those with incomplete response to medical treatment.

A case of tuberculous pyomyositis that caused a recurrent soft tissue lesion localized at the forearm.

We present the case of a 20-year-old male who had a non-traumatic soft tissue lesion (4 x 3 cm) with recurrent discharge at his right posteromedial antebrachial muscles; the patient underwent surgery twice, and antibiotic therapy was administered, but no cure was achieved with these treatments. The patient underwent surgery at our medical center. There was no history of pulmonary, gastrointestinal, or genitourinary tuberculosis (TB). Due to suspected pulmonary, genitourinary, and gastrointestinal TB, radiography and computed tomography scans were performed, and these studies disclosed no evidence of a primary origin. The erythrocyte sedimentation rate and the results of purified protein derivate testing were normal. We also detected submandibular lymphadenopathy (LAP) (2 x 3 cm) localized at a submandibular site in our patient 4 months after his first visit to our clinic. Smears were stained with Ehrlich Ziehl Neelsen (EZN) stain and culture were grown for Mycobacterium tuberculosis complex (MTC); the samples used for these assays had been obtained by incisional biopsy of the forearm lesion and by aspiration of the submandibular lymph node, and they were found to be MTC-positive. Then, a culture for MTC, derived from an induced sputum sample, was found to be positive, despite the negative results obtained with a sputum smear subjected to EZN staining. According to these results, the primary focus of the tuberculous pyomyositis and the submandibular LAP was the lungs. The lesion and submandibular LAP were both treated successfully by the administration of antituberculous chemotherapy.

Scrofuloderma of the lower extremity treated with wide resection: a case report and review of the literature.

Scrofuloderma is tuberculosis of subcutaneous tissue that ulcerates and drains through the overlying skin. It most commonly occurs in the neck from a cervical lymph node source. Although such lymphatic spread is the usual clinical picture, there are sporadic reports in the literature of direct hematogenous seeding of subcutaneous tissue forming a tuberculoma, or "cold abscess." Definitive diagnosis requires the identification of Mycobacterium tuberculosis within the suspect lesion. Surgical intervention is necessary in any draining lesion and should be accompanied by appropriate antituberculous chemotherapy. Accounts of bone and joint involvement are numerous, but the orthopedic surgeon must also be aware of the soft-tissue manifestations of tuberculosis and the indications for surgery. We report on an immunocompromised patient who presented with a rare case of scrofuloderma of the lower extremity, which was treated with wide resection.

[Recurrent soft tissue infections after accidental inoculation with BCG vaccine]. / Rezidivierende Weichteilinfekte nach akzidenteller Inoculation mit BCG-Impfstoff.

Complications after BCG vaccine (bacilli Calmette-Guérin) occur rarely. They can reach from a local acute abscess to chronic ulceration's. Therapeutically concepts of these complications range from conservative to operative treatment. In the following case history recurrent soft tissue infections occurred after accidental inoculation with BCG vaccine. The time course of these recurrent infections with its therapeutic options is discussed and a treatment strategy is suggested. Currently, radical excision combined with antituberculotic treatment seems to be the most promising therapy of this specific soft tissue infection.

[Buruli ulcers in rural areas of Bénin: management of 635 cases]. / Les ulcères de Buruli en zone rurale au Bénin: prise en charge de 635 cas.

Over the last six years we have treated 635 cases of Buruli ulcer at the Health and Nutrition Center of Zagnanado located in a rural area of southern Benin. Two thirds of cases involved children or adolescents from damp, swamp-land areas. The large size of this series and the fact that the number of cases increased yearly underlines the epidemic nature of this disease in Benin. Surgery was the only effective treatment and should be performed as early as possible. In our series of 635 cases wide excision of the ulcer and surrounding tissue was performed 797 times and was followed by skin grafting using thin skin grafts in 574 cases. Antibiotic treatment was begun immediately in order to avoid or treat secondary infection which can be severe. Despite the primitive facilities available, in particular the necessity to harvest skin grafts using a plain razor blade, all patients recovered except 5 who died of intercurrent infection. Our experience confirms the efficacy of early treatment of the ulcer by wide excision associated with antibiotic treatment and followed by skin grafting using fine grafts.

[Manifestations, diagnosis and treatment of non-tuberculous mycobacterial infections in non-immunodepressed patients]. / Manifestations, diagnostics et traitements des mycobactérioses non tuberculeuses chez le sujet non immunodéprimé.

Non-tuberculous mycobacteria (NTM) can be the etiologic agents of chronic pulmonary disease, lymphadenitis, skin and soft-tissue infection and disseminated disease in non-immunocompromised patients. The recognition of disease needs repeated isolation of the NTM from bronchopulmonary secretions or from tissue biopsies, and its identification by specific laboratory methods. A wide spectrum of clinical presentations and severity of disease can be found, from spontaneous healing to progressive and destructive lung disease, and death, according to predisposing conditions and mycobacterial species. The choice of surgical and drug treatment will depend on identification of specific pathogen and clinical evaluation.
