别诊断要点，并复习相关文献。结果：患者主要临床表现为间断性多关节肿痛3 年，加重伴发热3 个月。体格检查发现患者有多发
性皮下结节、多关节肿胀压痛。左腕、左肘皮下结节活检，经HE染色后光镜查见大量肉芽肿性病变，有的多核巨细胞内查见被吞

维血管周围可查见残留分化成熟的淋巴细胞及少数嗜酸性粒细胞。刚果红、PAS 染色均为阴性。偏光显微镜下，刚果红未查见绿

| Objective:To study the clinicopathologic characteristics of gout.Methods:The pathogenesis mechanism, clinical manifestations,
histological features, Congo red staining and Periodic Acid Schiff (PAS) staining results of a patient suffering fromgout were
analyzed, with review of the related literatures.Results:A 18-year-old young man complained that multiple joints swelling and pain discontinuity
more than 3 years, aggravating associated with fever for 3 months. Physical examination showed that there were many subcutaneous
nodules and multiple joints were painful swellings on pressure. The patient was taken to the operating room for excisional biopsy
of left wrist and elbow subcutaneous nodules. Stained with Hematoxylin and eosin (H&E), we found multiple granulomatous diseases
and foreign bodies in some multinucleated giant cells by microscopic. We also saw homogeneous materials that were monosodium urate
monohydrate (MSU) crystals in some focus with a surrounding foreign body giant cells and fibrous connective tissue consistent with gout.
Around the nodules, there were fibrovascular tissue surrounding by a few neutrophils and residual mature differentiation lymphocytes.
Congo red staining and Periodic Acid Schiff (PAS) staining were all negative. However, we found many pale yellow crystals with strong
birefringent under microplariscope by Congo red staining. The crystals presented clavate or fusiform.Conclusion:Gout has many pale
yellow crystals with strong birefringent under microplariscope by Congo red staining. Whether it is characteristic pathological changes by
Congo red staining in gout, there is no report about it up to now.We will collect more and hope more attention to it fromfellows. |
