Peritoneal keratin granuloma is a rare lesion included under granulomatous lesions of the peritoneum. It can be of infectious and non-infectious etiology. The lesion presents as a large intra-abdominal necrotic mass often misinterpreted clinically as a disseminated carcinoma. We report a case of peritoneal keratin granuloma in a 50-year-old male following peritonitis. Histomorphology revealed l...

Granuloma annulare is self-limiting cutaneous condition of unknown etiology, causing necrobiotic dermal and subcutaneous papules. A number of conditions have been described in association with Granuloma annulare, including lymphoma, anemia, intestinal bleeding, seronegative arthralgia, vasculitis and autoimmune thyroiditis. This manuscript, as the first report of this combination in Iran, descr...

Tick bite is known as a possible cause of some infectious diseases such as Lyme disease, spotted fever and related illnesses. The reaction to a tick bite may persist for several months to several years and can sometimes cause histopathological granuloma. The long-term reaction to salivary extracts from the tick could be responsible for development of granuloma in our patient. We recommended com...

Synthetic fibre granuloma of the conjunctiva, sometimes known as 'teddy bear granuloma', results from granulomatous foreign body reaction of the conjunctiva to synthetic fibres. It is often an incidental finding, most commonly found in children, is unilateral, and occurs in the lower eyelid. We present here, what we believe is the first reported case of synthetic fibre conjunctival granuloma in...

Actinic granuloma is a rare granulomatous reaction that is more commonly seen in females and thought to occur as an autoimmune response to actinic damage of elastic tissue. We discuss a case of a patient with actinic granuloma presenting with concomitant temporal arteritis. Our case and review of the literature emphasize the association between actinic granuloma and temporal arteritis, a seriou...

Cholesterol granuloma is an inflammatory reaction to cholesterol crystals deposition. It may develop in a variety of sites including the middle ear, mastoid process or even paranasal sinuses. Very few cases of cholesterol granuloma occurring in the jaws were reported. This report presents a rare case of cholesterol granuloma that developed in the wall of a large mandibular dentigerous cyst. The...

Pulmonary tuberculosis, caused by Mycobacterium tuberculosis (M.tb) represents a leading global health concern, with 8.7 million newly emerging cases, and 1.4 million reported deaths annually. Despite an estimated one third of the world's population being infected, relatively few infected individuals ever develop active clinical disease. The ability of the host to remain latently infected while...

The pyogenic granuloma is a clinical entity which originates as an overexuberant connective tissue response to a stimulus or injury.^ Trauma and local irritation have a significant impact on the development of the pyogenic granuloma. This lesion is particularly important to dentists because of its common intraoral occurrence and sometimes alarming clinical course. The pyogenic granuloma is seen...
