Non-tuberculous mycobacterium has a wide-spread occurrence in nature, and skin, soft tissue, bone, lung and disseminated infection can be involved. Non-tuberculous mycobacterium infection occurs both in immunocompetent patients without underlying diseases and in immunocompromised hosts. Non-tuberculous mycobactrial osteomyelitis is a rare cause of granulomatous osteomyelitis, and has been previously reported in the sternum, spine, humerus, femur, tibia or metatarsal. Mycobacterium abscessus osteomyelitis is a very rare infection in the foot and only 1 case has been reported. Authors report a case of Mycobacterium abscessus osteomyelitis involving the tarsal and metatarsal bones in a non-immunocompromized middle aged women.

Primary tuberculous osteomyelitis involving the mandible represents less than 2% of skeletal locations. In this paper, we report a case of mandibular tuberculosis (TB) detected after histopathological analysis of the surgically resected specimen during surgical management of a suspected case of ameloblastoma. A 14-year-old male patient presented to us with history of right-sided chin swelling. The clinical examination revealed a swelling, involving right body and parasymphysis of mandible, measuring approximately 6 cm in length and 2 cm in width, extending from right lateral incisor till the first molar. Radiological scans revealed a large multiloculated osteolytic expansive lesion measuring 52 × 20 × 18 mm. Excision of the lesion was performed and reconstruction was done with iliac bone grafting. The histopathological findings revealed a granulomatous lesion, suggestive of tuberculous osteomyelitis. The patient was successfully treated with standard multidrug therapy. One year after completion of therapy, there were no signs of recurrence. Primary mandibular TB is an extremely rare entity. Its clinical presentation is not specific. Radiologically, TB has no characteristic appearance. The positive diagnosis is based on histology. Primary mandibular TB is rare and should be kept among differential diagnoses in susceptible population and in endemic areas.

Tuberculosis is a systemic disease with a world-wide distribution, and its occurance in the oral cavity is well documented in the literature. Disease of oral cavity and jaw caused by Mycobacterium tuberculosis is very rare, so it is often difficult to diagnose tuberculosis in the oral cavity. When granulomatous and ulcerative lesion persists in the oral cavity for a long time, it may be considered a tuberculosis. When differential diagnosis is needed, the most reliable indicators of mycobacterial infection are careful clinical evaluation, skin test, acid-fast staining, biopsy and culture. We report a case of tuberculous osteomyelitis which simultaneously occurred on the maxilla and mandible in a 85 years old man that proved diagnosis difficult, but which responded very well to surgical treatment and chemotherapy.

Empyema necessitatis refers to empyema that extends into the extrapleural space through a defect in the pleural surface. Tuberculous empyema necessitatis is a rare complication of tuberculosis. We experienced a 21-month-old boy with tuberculous empyema necessitatis with osteomyelitis in the right $7^{th}$ rib. He presented with a mass on the right lateral chest wall, which was soft and nontender, enlarging for one month. He also had mild fever. The plain radiograph of his chest revealed soft tissue swelling and calcified lymph node on the left axilla, and his PPD skin test was positive. CT scan of the chest showed empyema necessitatis at the right lower chest and upper abdominal walls with osteomyelitis of the right $7^{th}$ rib. He did not have concurrent pulmonary tuberculosis. Surgery was performed for diagnosis and treatment. In histopathologic findings, chronic granulomatous inflammation with caseation necrosis was shown and was positive for acid fast bacilli stain. In addition, M. tuberculosis complex was found as etiology by polymerase chain reaction. The patient has been treated with anti-tuberculous medication without any specific complication.

Halicephalobus gingivalis is a free-living nematode that occasionally causes infections in horses. We report a rare case of limb fracture of horse caused by infection with H. gingivalis. An 8-year-old mare was referred to the Veterinary Hospital of the Federal University of Lavras with claudication grade 5 of the right hind limb, that had been started 3 months ago. The patient had aseptic arthritis in the tarsal joint and edema that extended to the quartile. The radiographic examination showed punctate osteolysis with exacerbation of bone trabeculation along the calcaneus, talus, proximal epiphysis of the third metatarsal and distal epiphysis of the tibia. Treatment for arthritis was initiated, and the animal showed a slight improvement in limb function. However, 21 days after hospitalization, due to a comminuted fracture of the tibia, it was euthanized. At necropsy, yellowish masses were found from the metatarsal to the tibia, and around the tarsal bones and joint. Similar masses were also found in the left kidney. Numerous nematodes compatible with H. gingivalis were identified. This is the first description of a pathological fracture caused by H. gingivalis infection in an equine limb.
