the larvae causing myiasis can lead extensive tissue destruction, invasion into deep tissues and secondary infections. poor hygiene, low socioeconomic condition and presence of open wounds are the most important predisposing factors. this case report describes destructive wound myiasis in a 58-year-old male patient diagnosed with maxillary sinus squamous cell carcinoma who lives in a rural are...
this report is related to a female 7-year-old crossbreed sheep whose right eye had been protruded andswelling of upper eyelid was observed. routine enucleating was performed. histopathological evaluation ofeyelid revealed coincidence of two kinds of neoplasms. the first part was composed of multiple lobules ofsebocytes, which were detected as meibomian adenoma. the second section included infil...
introdouction: oral squamous cell carcinoma (oscc), the most common form of oral cancer, requires early diagnosis and suitable treatments. fascin is a protein involved in cell adhesion and is increased in expression in certain types of carcinomas. the present study was conducted to assess fascin expression in oscc using an immunohistochemical technique. materials and methods: in the present ret...
Primary squamous cell carcinoma of the kidney is very rare. Due to the lack of clinical signs, diagnosis and treatment is often delayed. Because of the nature of invasive squamous cell carcinoma, most patients experience metastasis and recurrence. Prognosis of the disease is poor and survival of patients has been reported less than 5 years. We report a squamous cell carcinoma with a staghorn st...
background and objective: cutaneous cytology is the study of scraping or smears obtained from skin lesions. although not commonly employed, cutaneous cytology has been a useful tool for clinicians due to simplified procedures and high sensitivity and specificity of presurgical clinical diagnosis of common types of skin tumors. this investigation was conducted to study usefulness of cutaneous cy...
introduction: granular cell tumors (gcts) are rare and mostly benign soft tissue tumors. though they have been reported in all parts of body, they are generally located in the head and neck region, especially on the tongue. some malign forms exist, but these have been rarely reported. granular cell tumors have a neural origin and, in immunohistochemical evaluations, they express s-100 and neuro...
Epidermolysis bullosa (EB) is a group of dermatological conditions characterized by development of bullae and ulcers following trivial trauma. One of the most important complications of EB is squamous cell carcinoma. While occurance of skin squamous cell carcinoma is common in epidermolysis bullosa, its occurence on mucosal surface is rare. Herein, we report two members of a family who develope...
Background and Aim: Microscopic differentiation between well differentiated squamous cell carcinoma and verrucous carcinoma is very difficult. As these lesions have different clinical course and treatment a reliable method to help distinguish between them is necessary. The basement membrane in oral verrucous carcinoma is generally intact whereas in oral squamous cell carcinoma is mostly discont...
Background and purpose: Mast cells as the multi-functional and complex cells play a key role in tumor progression. Due to the higher malignant potential of Oral Squamous cell carcinoma (OSCC) compared with cutaneous squamous cell carcinoma (cSCC), the purpose of this study was to compare the mast cells count in squamous cell carcinoma of the skin and oral cavity and evaluate their correlation w...
Background & Objective: Laryngeal squamous cell carcinoma (LSCC) is considered to be one of the most common cancers of the head and neck, accounting for roughly 90% of all malignant tumors of the larynx. To have a timely diagnosis for a better and practical therapy, molecular markers have to be investigated. The aim of this study was to determine the expression of Cyclin D1 (CD...
