Introduction & Objective: Actinomycosis is an indulent , slowly progressive infection caused by anaerobic or microaerophilic bacteria that normally colonize the mouth,colon and vagina.The most common location for diagnosed actinomycosis is the perimandibular region . Oral cervicofacial disease can be manifested as a mass lesion . Actinomycosis should be considered in the differential diagnosis of any mass lesion in the head and neck region . Bacteriologic identification from a sterile site or detection of sulfur granules accompanied by microorganism confirms the diagnosis. Case : this patient is a 11 old years boy that presented with nearly painless mass on right temporal area of the scalp and trismus that develop ed from ten days ago . skull and brain CT scan showed a subcutaneous swelling without bone and brain extension . Blood indexes were normal except ESR that was 55mm in first hour . Pathology of complete mass excision showed actinomycosis and after high dose penicillin therapy parenteral route normalized ESR and the patient had not any problem in follow up. Conclusion : Atinomycosis can manifest as a progressive painless mass of the scalp that easily diagnosed as a neoplasm .

Background: Inflammatory PSEUDOTUMOR (IPT) is a benign lesion with potential of recurrence and continuous growth. Its clinical and pathologic features resemble malignancies. The present study was conducted in Shaheed Beheshti University of Medical Sciences to determine the status of IPT. Materials and methods: During this descriptive study, the pathology reports of Shaheed Beheshti university teaching hospitals were reviewed from early 1993 to the end of 1998 and 20 cases of inflammatory PSEUDOTUMOR were found. Results: The study population included 12 females and 8 males with the mean age of 20 years. 8 cases (40%) were occurred in lung, whereas 12 (60%) were in extra pulmonary regions. 16 had anemia, whereas weight loss and anorexia were reported in 7 cases (35%). Most of the adults had undergone operation with preoperative diagnosis of malignant tumor, however, most of the children received treatment with the probable diagnosis of recurrent pneumonia. Conclusion: Since wide spectrums of benign and malignant tumors are considered as IPT differential diagnosis, suitable preoperative studies such as immunohistochemistry and flowcytometery are highly recommended.

Background and Objectives: PSEUDOTUMOR cerebri is defined by the increase of intracranial pressure. It has different atiologies but, many of its causes are idiopathic and typically present on young obese females. Cerebrospinal fluid (CSF) analysis was normal in this case study and there was no evidence of intracranial mass, venous sinus thrombosis, or obstruction in CSF stream.In this study, we have reported a case of PSEUDOTUMOR cerebri presented 7 years after a successful kidney transplant, under treatment by Cyclosporine, Methylprednisolon and Azathioprine(AZT).Case Report: The patient was a 17-year old obese female with a body mass index of 30kg/m2 having PSEUDOTUMOR cerebri 7 years after a successful kidney transplant. Brain imaging like CT scan & MRA (Magnetic Resonance Angiography) were normal. CSF analysis was normal, but the increase in CSF pressure had been detected. Repetitive lumber punctures were performed with simultaneous Acetazolamid administration. But her headaches were treated even after the continuation of Cyclosporine and Methylprednisolon, anemia, and renal failure. For patients with kidney transplant and headaches, it is necessary to rule out PSEUDOTUMOR cerebri as a differential diagnosis. Neurotoxicity of Cyclosporine is not rare and we have to pay close attention to neurologic side effect of this drug as well. After diagnosing PSEUDOTUMOR cerebri in such patients, it is necessary to limit the progression of symptoms and avoid the decrease in patient 's visual acuity.

Inflammatory pseudotuomr refers to a group of benign tumor like lesions that they are composed of a mixed inflammatory infiltrates. The diagnosis of these lesions and differentiation of them from malignant process may be difficult. We report on a 35-yearold man who presented with multiple painless palpable masses in his right hemiscrotum for about 6 months. Right epididymal involvement with intact testicle and spermatic cord were observed during scrotal exploration. After classic right epididymectomy, histopathologic studies revealed inflammatory PSEUDOTUMOR of the right epididymis. No remarkable abnormal signs and symptoms were observed in the follow up visits after 8 months.

Primary inflammatory PSEUDOTUMOR of the central nervous system is extremely rare. These lesions may be intra-axial, extra-axial, or a mix of them. We report a case of intracranial inflammatory PSEUDOTUMOR involving both brain parenchyma and dura.

Introduction: Haemophilia is one of the hereditary recessive diseases linked to sex-induced coagulation disorder and is characterized by bleeding episodes. This report presents a rare involvement of the distal phalanx hemophilic PSEUDOTUMOR. Case Presentation: A 21-year-old man was crushed by a closing door 18 months before. The distal phalanx was fractured, and a large hematoma developed under the nail plate, which separated the nail plate from its bed. Eighteen months after the injury, plain radiographs demonstrated an expansile lesion with extensive destruction of the distal phalanx. Regarding the patient’, s history and abnormal clotting tests, the development of a hemophilic PSEUDOTUMOR was considered at the distal phalanx due to the enlarging nature of the coagulum, which induced compression and pressure necrosis on the adjacent bone and structures. Conclusions: Hemophilic PSEUDOTUMORs in the small bones are rarely reported. After a minor traumatic injury in hand, exact management and coagulopathy control are important to prevent further complications.

PSEUDOTUMOR cerebri syndrome (PTCS) is an uncommon disease in children. On-time diagnosis and treatment can prevent irreversible visual loss. Although headache is the most common complaint of children with this syndrome, the present case report reported a child with neck rigidity and torticollis, declined by the reduction of intracranial pressure. Despite the importance of torticollis and neck rigidity presented in various significant neurological disorders in need of thorough investigations, in the case of unexplained symptoms of those disorders, it is recommended to consider fundoscopic examinations for PTCS to prevent its vital complications.

Introduction PSEUDOTUMOR Cerebri (PTC) is a condition characterized by increased intracranial pressure (ICP). It is mainly found in overweight women of childbearing age. In this study, a case of PTC in pregnancy was reported. Case presentation The patient was a 26-year-old pregnant woman weighing 70 kg in the 19th week of pregnancy with symptoms of diplopia, headache, and transient visual obscuration who referred to the gynecologist. The gynecologist checked the patient for pregnancy poisoning and after tests, it was determined that she did not have pregnancy poisoning. After referring the patient to an ophthalmologist, the patient was diagnosed with PTC. The treatment form the neurologist's view was drug therapy or LP that the gynecologist did not allow to use drug and LP treatment was selected for the patient. During pregnancy, the patient underwent LP for 9 times. During pregnancy, no drug was prescribed for psedotomor cerebri due to obstruction by a gynecologist and the disease was controlled only by LP. The patient underwent cesarean section under spinal anesthesia by diagnosis of a anesthesiologist and the baby weighed 3400 g was born with a first minute Apgar score of 9 and a fifth minute Apgar score of 10. Conclusion Although the pathology of psedotomor cerebri has not been fully identified yet, but various treatment methods have been mentioned to prevent the progression of this disease. In the present study, the reported patient was controlled with regular follow-ups and performing LPs. The maternal and fetal complications following somatomerber were well controlled.
