口底部自發性鈣化－病例報告

本篇提出一個在口底部肌肉層出現的許多鈣化顆粒的病例。患者在就診時曾被誤以爲是唾液腺導管結石，但經造影及核磁共振檢查發現兩側頷下腺體正常、導管分泌也正常、血液檢查正常，且血鈣、血磷、alkaline phosphate、副甲狀腺激素及腎功能都在正常值內。手術後經病理檢查發現，這些鈣化體周圍的包覆結締組織有骨化細胞的出現，在排除唾液腺導管結石及病理性鈣化所引起的因素後，最後診斷爲口腔底部自發性鈣化，是一個罕見病例。

Calcification in soft tissue is an unusual clinical finding. It is divided into two types: idiopathic and pathologic. Idiopathic calcification is a deposition of calcium salts in normal tissue, but it has unknown of pathogenic mechanism. There are two broad categories of pathologic calcification: Dystrophic and Metastatic calcification. Dystrophic calcification is the more common form and results from deposition of calcium salts in injured, degenerated or dead tissue. Metastatic calcification (calcinosis) is the deposition of calcified product in normal tissue, as a result of hyperphosphotemia, or end stage of renal disease, with or without concurrent hypercalcemia. We present a case of multiple calcinosis appeared in the mouth floor. We find no underlying cause for the calcification could be identified which probably represents as a pathologic calcification factors and exclusion of myositis ossificans traumatica disease. Therefore, we think that it might be an idiopathic calcification.
