Sciatic nerve symptomatology may arise from both intra- and extra-neural pathology, at any point along descent from the sacral plexus to its bifurcation. The potential aetiology is broad, ranging from degenerative spinal disease to muscle, bony and vascular pathology. We present an extremely unusual case of position and exercise-induced nerve compression secondary to arteriovenous malformation and review the potential extraspinal causes, many of which may be ameliorated by surgical excision or decompression. We further discuss the usefulness of diagnostic imaging, specific clinical tests and histopathological tools that may aid in management.

ABSTRACT Objective: To evaluate the effects of right sciatic nerve compression and cryotherapy on muscle tissue. Methods: We used 42 male Wistar rats, subdivided in the following Groups Control, Injury 3, Injury 8 and Injury 15 submitted to nerve compression and euthanized in the 3rd, 8th and 15th day after surgery. The Cryotherapy Injury 3 was entailed treatment with cryotherapy by immersion of the animal in recipient for 20 minutes during 1 day, then animals were euthanized at the 3rd day after surgery, and the Cryotherapy Injury 8 and the Cryotherapy Injury 15 was treated for 6 days, and euthanized at the 8th and 15th day after surgery. Functional evaluation was performed by the grasping strength of the right pelvic limb. The right tibialis anterior muscles were evaluated for mass, smaller diameter and cross-sectional area. In the Cryotherapy Injury 8 and the Cryotherapy Injury 15 groups, the hydroxyproline was dosed in the right soles. Results: In the compression there was a significant difference in the Injury Groups compared with the Control Group (p<0.05). In the smaller diameter, the compression in Control Group was higher than Injury 8 (p=0.0094), Injury 15 (p=0.002) and Cryotherapy Injury 15 (p<0.001) groups. The comparison between groups with euthanasia in the same post-operative period, a significant difference (p=0.0363) was seen in day 8th after surgery, and this result in Cryotherapy Injury Group was greater than Injury Group. In the fiber area, Control Group was also higher than the Injury 8 (p=0.0018), the Injury 15 (p<0.001) and the Cryotherapy Injury 15 (p<0.001). In hydroxyproline, no significant difference was seen between groups. Conclusion: Nerve damage resulted in decreased muscle strength and trophism, the cryotherapy delayed hypotrophy, but this effect did not persist after cessation of treatment.

Introduction Mesenchymal tumours of submandibular gland are extremely rare. Schwannoma of the salivary glands is a particularly rare form of an extracranial neurogenic tumour.  Case Report Here, we present an unusual case of schwannoma of submandibular gland in a 16 year old girl, who underwent total excision of mass with submandibular gland excision with no cranial nerve deficits. The details of the histopathologic features are present .   Discussion Schwannoma of the salivary gland is a particularly rare form of an extracranial neurogenic tumour. Our case indicates good prognosis in a case of submandibular gland schwannoma after surgical excision.

Endemic Areas

At least 27 million men present with urogenital manifestations of genital filariasis (GF). Although there is a large burden of GF in residents in endemic regions, infection in short-term travellers and in non-endemic areas is rare. We report the case of a 75-year-old Italian man referred to our institution for a testicular discomfort. Clinical examination and ultrasound detected a mass of 40×18 mm in the scrotum without signs of varicocele, hydrocele and testicular or epididymal abnormalities. After ineffective medical treatment, the patient underwent surgical excision. Histology demonstrated filarial granuloma with thick cuticles pathognomonic of an adult worm in the testicular tunics. Surgery has a fundamental role in localized cases of GF to remove nematodes from the fibrotic nodules. The present manuscript describes a singular case of GF observed in Italy in a non-immigrant patient with evidence of remnants of an adult worm in the testicular tunics. SIMILAR CASES PUBLISHED: 11

Rare Lesion

Keloid scarring is a benign hyperproliferation of fibrous tissue occurring at a wound healing site. Keloid formation related to the ear is generally the result of ear-piercing, mainly causing cosmetic disfigurement. We present an unusual case of keloid formation at a previous meatoplasty incision scar in a 10-year-old Caucasian with a modified radical mastoid cavity. This lesion prevented the cavity from self-cleaning and obstructed microscopic evaluation of the cavity. Treatment was successfully performed by surgical excision, with closure of the defect using supra-keloid skin flaps, followed by serial steroid injection therapy.

Palatal swellings are rare in children and the incidence differs from that of the adult counterparts. When the palatal swellings do arise in children, they usually are palatal abscess from periapical region, and few cases like pleomorphic adenoma in young adults have also been reported. But inflammatory fibrosis of palate in children is a rare occurrence. Inflammatory fibrosis is formation of excess fibrous connective tissue in an organ or tissue, as a reparative or reactive process. This report describes an unusual case of iatrogenic inflammatory fibrosis on the palate due to extraction of tooth number 22 in a 13-year-old female patient. The patient presented with a single large well-circumscribed oval palatal swelling that was soft, fluctuant, not fixed, and nontender. Surgical excision of the lesion was done and it was sent for histopathological assessment. The biopsy showed fibrous tissue with collagen fibers, spindle shaped fibroblasts, neovascularization, RBCs, chronic inflammatory cells, and traces of salivary gland and nerve tissue.
