Multifocal bilateral xanthogranulomatous osteomyelitis.

Xanthogranulomatous osteomyelitis is a rare chronic inflammatory disorder which clinically resembles bone tumor. It is characterized histologically by the presence of a large number of foamy histiocytes admixed with lymphocytes and plasma cells. Xanthogranulomatous inflammation can involve any organ, with kidneys and gall bladder being the worst affected.

Immunohistochemistry, a valuable tool in detection of cervical lymph node micrometastases in head and neck squamous cell carcinoma: a prospective study.

The regional failure after comprehensive clearance of neck metastasis and consequent pathological report of N0 disease has been reported fairly frequently. The role of recurrence of disease in the neck in the cases has been variously reported by different authors. The light microscopy does not detect the micrometastasis and the specimen is reported negative for metastasis.

Myoepithelial cell-rich pleormorphic adenoma of minor salivary gland of parapharyngeal space.

Parapharyngeal space tumors are rare and constitute only 0.5-1.0% of head and neck tumors.

ESCC with metastasis in the young age of caustic ingestion of shortest duration.

Introduction: Squamous cell carcinoma arising from caustic ingestion in the esophagus in young age of very short duration is not reported in literature.

Case Report: We present the world's first reported case from India of a 14-year-old boy with an associated 1-year history of accidental caustic ingestion who developed esophageal squamous cell carcinoma along with cervical lymph node metastasis, after a thorough review of available literature.

Discussion: Accidental caustic ingestion may have an unusual presentation and severe complications, but a favorable outcome.
