Sternoclavicular Tuberculosis: An Unusual Presentation.

Extra pulmonary tuberculosis is on the rise worldwide, and younger patients, are females. And people from Asia and Africa are at high risk. Sternoclavicular TB is extremely rare, even in countries that have a high prevalence of TB. It can be in the absence of pulmonary TB. It has a varied clinical presentation. Painless chest wall swelling can be the presenting symptom of sternoclavicular diagnosis. Ultrasonography and high-resolution computed tomography can identify the nature of the lesion and the extent of bone involvement. Aspiration from the swelling or histopathology examination is mandatory for diagnosis. Caseous necrosis is diagnostic of TB. Detection of acid-fast bacilli in smears or tissue or molecular methods is required for definitive diagnosis. A high degree of clinical suspicion is required for early diagnosis. The treatment of thoracic TB is the subject of controversy. Anti-tubercular drugs are the mainstay of treatment. Surgical intervention is basically for flattening cold abscesses and removing infected tissue, including affected bones and cartilage.

Image-guided fine-needle aspiration cytology or core biopsy - A key to definitive diagnosis of tuberculous mastitis.

Despite advances in the treatment, tuberculosis (TB) is still a global health problem. The diagnosis of extrapulmonary TB in their primary form is very challenging. Breast TB is very uncommon and accounts for < 0.1% of all breast lesions. Due to rarity of the disease and difficulty in diagnosis, we report a case of a 40-year-old female who had a hard lump in the right breast. Full-field digital mammography suggested the lesion as American College of Radiology Breast Imaging Reporting and Data System-5 (ACR BIRADS-5) (highly suggestive of carcinoma). Histopathological examination of multiple cores of the breast tissue showed lymphocytic inflammatory infiltrates confined to breast lobules. Fungal stains and Ziehl-Neelsen (ZN) stain were negative. A diagnosis of chronic mastitis with the possibility of autoimmune lobular mastitis was suggested. Subsequent image-guided fine needle aspiration smears showed epithelioid granulomas mixed with lymphocytes. Areas of amorphous-to-granular eosinophilic material (caseous necrosis) were seen at places. ZN stain showed acid-fast bacilli. A diagnosis of tuberculous mastitis was given.

Coexistence of Ectopic Tubal Pregnancy with Serous Tubal Intraepithelial Carcinoma: A Rare Case Report with Review of Literature.

Serous tubal intraepithelial carcinoma is a precursor lesion for high-grade pelvic serous carcinoma. The incidence is 0.6%-6% in tubectomy specimens of women who are BRCA-1,2 positive or have a strong family history of breast or ovarian cancer. STIC in women who do not have BRCA-1,2 mutations or concomitant high-grade serous carcinoma is exceedingly rare. Ectopic tubal gestation coexisting with serous tubal intraepithelial carcinoma is very rarely reported. These lesions pose considerable difficulty in the diagnosis. A combination of histology and immunohistochemical expression p53 and ki67 substantially improves the reproducibility of the diagnosis. Diagnosing these lesions will help identify potential at risk patients and their families for carcinoma. Adequate prolonged follow-up for incidental serous tubal intraepithelial carcinoma is the mainstay. We report one such case of a 31-year-old female who was operated for the right tubal gestation and found to have serous tubal intraepithelial carcinoma.
