The Purpose of current study to evaluate the incidence and treatment of conjunctival pyogenic granuloma after strabismus surgery. We retrospectively studied 512 consecutive patients who underwent strabismus surgery from 2004 through 2013.Pyogenic granuloma developed in 2 of 512 patients (0.39%). In one patient, who presented with pyogenic granuloma on the exposed sclera located at the original ...

introduction: mycobacterium marinum infection is the most common nontuberculous mycobacterial skin lesions. it results from skin injury and contact with contaminated water, fish, or shellfish; its infections have low frequency, nonspecific symptoms and lack of specific identification methods that can alter correct diagnosis.this study designed about cases that reported from iran and comparing t...

Pyogenic granuloma is thought to represent an exuberant tissue reaction to local irritation. It occurs in second decade of life in young females. Clinically, oral pyogenic granuloma is a smooth or lobulated exophytic growth, pedunculated or sessile, which usually bleeds on provocation. Oral pyogenic granuloma preferentially affects the gingiva. On rare occasion, it can be found extragingivally ...

The tuberculous granuloma is an elaborately organized structure and one of the main histological hallmarks of tuberculosis. Macrophages, which are important immunologic effector and antigen-presenting cells, are the main cell type found in the tuberculous granuloma and have high plasticity. Macrophage polarization during bacterial infection has been elucidated in numerous recent studies; howeve...

Introduction: Mast cells are large granular cells that arise from a multipotent CD 34+ precursor in the bone marrow normally distributed throughout connective tissues. The most common method to study role of mast cells in any altered condition involves their identification and quantification in that condition and compare the values with that of the normal average count or number of mast cells. ...

Inclusion body myositis is a form of inflammatory myopathy. We identified 4 cases of inclusion body myositis showing granuloma formation in muscle tissue and aimed to assess the features of this atypical form of inclusion body myositis. We retrospectively reviewed consecutive patients who satisfied European Neuromuscular Centre IBM Research Diagnostic Criteria 2011. Then, we assessed clinical p...

BACKGROUND Hepatic granuloma is reported in 2 - 15% of liver biopsy specimens. It is relatively easy for the pathologist to diagnose, but sometimes arriving at a specific etiology is quite difficult. Until now, there are few published studies about the etiology of hepatic granuloma in Iran. In this study, we attempt to determine the causes of hepatic granuloma from one of the largest referral c...

Sarcoidosis is a granulomatous disorder of unknown cause, affecting multiple organs, but mainly the lungs. The exact order of immunological events remains obscure. Reviewing current literature, combined with careful clinical observations, we propose a model for granuloma formation in pulmonary sarcoidosis. A tight collaboration between macrophages, dendritic cells, and lymphocyte subsets, initi...

Sarcoidosis, a systemic granulomatous disease of unknown etiology. The presentation of sarcoidal granuloma in neck nodes without typical manifestations of systemic sarcoidosis is difficult to diagnose. We describe the case of a 37-year-old woman with an increasing mass on the right side of neck. The excisional biopsy from the neck mass showed noncaseating epithelioid cell granuloma of the lymph...
