ABSTRACT
Adenoid cystic carcinoma, an uncommon malignant salivary gland neoplasm, is known for its long clinical course, indolent growth, local recurrence and late distant metastasis. We report an unusual case of adenoid cystic carcinoma of the palate in a 64-year-old woman, undiagnosed for more than 15 years, who presented as malignant pleural effusion.

An 18-year-old man presenting with paraplegia due to spinal epidural infiltration at D6-D7 underwent laminectomy and spinal decompression followed by near-complete resolution of neurological symptoms; but this resolution was followed by progressively enlarging cervical lymph nodes. Leucocytosis, an elevated erythrocyte sedimentation rate, a marked polyclonal hypergammaglobulinemia and a moderate hepatosplenomegaly were found. The diagnosis of sinus histiocytosis with massive lymphadenopathy (SHML), also known as Rosai-Dorfman disease was established histologically by lymph node biopsy about 2 years after presentation.

Literal meaning of artefact given by 'Oxford Advanced Learner Dictionary' is 'a thing made by people'. In medical science 'the fact' is not true; but we observe routinely is called artefact. We face various types of artefacts in daily reporting of pathology specimen. Many times artefacts hinder the actual diagnosis. The artefacts i. e. fixation artefact, processing artefact, staining artefact, mounting artefact, air bubbles etc. can cause difficulty in diagnosis and a pathologist should be trained to identify those artefacts.
