Prostatic abscess: report of a case and review of the literature

Prostatic abscess is an uncommon entity nowadays due to widely use of antibiotics, however, in some patients, because of the seriousness, a quick diagnosis and interventionist treatment is required. We report a case of a 78 year-old male patient who had a torpid evolution and needed an urgent prostatectomy. We review ethiopathogenic factors, clinical findings, diagnosis and treatment of this uncommon entity.

Prostatic carcinosarcoma: case report and review of literature

True carcinosarcoma of the prostate is a rare neoplasm, with only 9 cases well documented by immunocytochemistry and ultrastructural examination. We report a case of an unresectable pelvic tumor studied at autopsy. The primary prostatic neoplasm and pulmonary metastases were composed of well differentiated adenocarcinoma admixed with foci of leiomyosarcoma and osteosarcoma. The sarcomatous components showed reactivity with vimentin and desmin, did not express prostatic acid phosphatase (PAP) and prostate specific antigen (PSA), and contained myofilaments on electron microscopic examination. Positive staining of the carcinomatous component for PAP and PSA was noted. These findings confirm the mixed epithelial and mesenchymal components in primary and metastatic sites, and support the diagnosis of true prostatic carcinosarcoma.     

Epidural abscess: case report and literature review

OBJECTIVE: To report a case of spinal epidural abscess complicating epidural analgesia, and to heighten awareness of the condition and the importance of early recognition and treatment. CASE REPORT: A 72-year-old woman underwent adrenalectomy and groin dissection for recurrent malignant melanoma under combined general and epidural anesthesia. On the fourth postoperative day, she developed signs of localized infection at the epidural site and a band of reduced sensation. Further neurological signs developed before the diagnosis was made by magnetic resonance imaging scan. She subsequently underwent emergency laminectomy and drainage of epidural abscess. CONCLUSION: Delayed diagnosis allowed the development of significant morbidity before neurosurgical intervention and antibiotics were instituted.     

Thyroid abscess: case report and review of the literature

A thyroid abscess is an infrequently encountered condition with a rarity that is attributable to anatomic and physiologic characteristics of the gland that impart a unique quality of infection resistance. The differential diagnoses for a painful thyroid is limited, with subacute and chronic thyroiditis being the most often-encountered processes. Acute suppurative thyroiditis with abscess formation, although rare, is a formidable clinical scenario with morbid complications. Because the diagnosis of a thyroid abscess is often delayed in lieu of investigating other more common etiologies of thyroiditis, this disease entity may portend to a dismal clinical outcome. The authors report the case of a 53-year-old woman with a thyroid abscess yielding a single microbial isolate believed to be resultant from a urinary tract bacteremia. They also review the literature for discussion of abscess etiologies, presentations, and management strategies.     

Ischemic intestinal involvement in a patient with Buerger disease: case report and literature review

A 42-year-old Japanese man who had undergone amputation of the left leg below the knee because of Buerger disease required emergency thrombectomy 7 months later. He complained of acute abdominal pain after thrombectomy. At aortography the distal superior mesenteric artery and its branches were not well visualized. Emergency laparotomy was performed because of suspected intestinal ischemia, and the terminal ileum and cecum and part of the ascending colon were resected. In total, the patient underwent laparotomy four times. Histopathologic findings revealed that the arteries and veins of the resected small intestine were occluded with organized thrombi. Inflammatory cell infiltration was recognized mainly in the intima. These findings are compatible with Buerger disease.     

Prostatic carcinosarcoma: A case report and review of literature

A unique case of carcinosarcoma of the prostate detected in a 71-year-old man is presented. Pelvic exenteration was performed, and the resected prostatic mass was found to consist of two histologically distinct elements; adenocarcinoma and sarcoma with focal osteosarcomatous element. The patient is still alive with neither metastasis nor recurrence. This is the 42nd case of carcinosarcoma of the prostate to be reported in the literature.     

Plantar fibromatosis: literature review and a unique case report.

Plantar fibromatosis represents a relatively uncommon benign lesion of soft tissue. It is most often found to invest the central and medial portions of the plantar fascia and commonly occurs in conjunction with other fibrous proliferate disorders. The authors present a detailed review of the literature concerning this usually unencapsulated fibrous growth. A unique case involving a relatively large encapsulated mass found to undergo dorsal extension into the plantar musculature is also presented.     

Psoas abscess: case report and review of the literature.

Psoas muscle abscess is rare and presents a diagnostic challenge requiring a high index of suspicion. We report an unusual case of primary psoas abscess caused by Proteus mirabilis. Primary psoas abscess is most commonly present in children and is usually caused by Staphylococcus aureus. A total of 434 cases of psoas abscess has been reported. The subject is discussed noting the differences between primary and secondary cases, and emphasizing the importance of ultrasound and computerized tomography guided drainage of psoas abscess. A flow chart for the evaluation and management of primary and secondary abscess is presented, taking into consideration the success rate of the various methods of treatment described in the literature.

Hepatic abscess in patients with chronic granulomatous disease

OBJECTIVE: To evaluate the clinical presentation, diagnostic procedures, and surgical management of hepatic abscesses in patients with chronic granulomatous disease (CGD). SUMMARY BACKGROUND DATA: Chronic granulomatous disease is a rare inherited primary immunodeficiency in which phagocytes cannot destroy catalase-positive bacteria and fungi. Defects in the phagocytic cells' respiratory burst lead to life-threatening infections, including hepatic abscess. These abscesses are recurrent and often multiple and are treated differently from bacterial abscesses in patients without CGD. METHODS: Between 1980 and 2000, 61 cases of hepatic abscess in 22 patients with CGD were treated at the National Institutes of Health. Clinicopathologic features were investigated by retrospective review of the medical records, radiographs, and histopathology. RESULTS: Twelve of the 61 cases were primary hepatic abscesses. Twenty-nine of the cases were recurrent hepatic abscesses, and 20 cases were persistent hepatic abscesses. The median age at the time of initial hepatic abscess presentation was 14 years. Subjective fever was the most frequent presenting symptom, and the erythrocyte sedimentation rate was elevated in 98% of cases. Fifty-two cases were managed surgically and eight cases were managed with percutaneous drainage. One patient refused surgery. The surgical complication rate was 56%; however, there were no deaths directly related to the hepatic abscesses. Staphylococcus aureus was the most frequent organism identified in culture (88% of positive cultures). Aggressive surgery and antibiotics ultimately resulted in successful treatment of all patients. CONCLUSIONS: Hepatic abscesses occurring in patients with CGD represent a difficult diagnostic and treatment challenge. Early excision and treatment with antibiotics directed against S. aureus is necessary. General surgeons should be aware of this rare immunodeficiency and should aggressively manage hepatic abscesses in these patients.     

Type II gall bladder perforation with abdominal wall abscess in a cirrhotic patient: case report and review of the literature

Gallbladder perforation is a rare condition even in patients affected by acute cholecystitis. Most patients who present with gallbladder perforations are diagnosed preoperatively by radiologic imaging. Morbidity and mortality for this condition has improved significantly over the last few decades. We encountered a cirrhotic patient who was affected by primary sclerosing cholangitis and who developed a type II gallbladder perforation before undergoing a cadaveric liver transplantation. In this article, we report her clinical course and our review of the current literature on this rare condition.     

Halo pin intracranial penetration and epidural abscess in a patient with a previous cranioplasty: case report and review of the literature.

STUDY DESIGN: Report of a patient with an epidural abscess after halo pin intracranial penetration at the site of a previous cranioplasty. OBJECTIVES: To report a rare case of intracranial penetration at the site of a previous cranioplasty associated with epidural abscess, and to discuss the diagnostic and therapeutic approach to its management. SUMMARY OF BACKGROUND DATA: The most serious complications associated with use of halo device occur when pins penetrate the inner table of the skull, resulting in cerebrospinal fluid leak and rarely in an intracranial abscess. However, no mention of intracranial halo pin penetration at the site of a previous cranioplasty was found in the literature. METHODS: A 64-year-old man with ankylosing spondylitis had a halo vest placed for management of a fracture dislocation through the C5-C6 intervertebral disc space associated with left C6 radiculopathy. One week later, the patient experienced fever and headache associated with pain, redness, and drainage at the site of the insertion of the left posterior pin. Computed tomography of the brain showed a 1.5-cm intracranial penetration of the halo pin through a previous cranioplasty of the temporal bone, associated with epidural abscess and cerebral edema in the left temporoparietal lobe. The pins and the halo vest were removed, the pin site was cleaned, and a Philadelphia cervical collar was applied. Staphylococcus epidermidis grew on the culture of drainage from the pin site. The patient started immediate intravenous antibiotic treatment for 2 weeks, followed by oral antibiotics for 2 additional weeks. RESULTS: The patient had gradual improvement of his symptoms within the first 48 hours. At the latest follow-up visit, he had fully recovered and his fracture had healed. CONCLUSIONS: The halo device should not be used for patients with a previous cranioplasty, especially if the pins cannot be inserted at other safe areas of the skull. A thorough medical history and physical examination of the skull are important before the application of a halo device. Computed tomography of the skull may be necessary before elective halo application for patients with concomitant head trauma, confusion, or intoxication and for patients with a previous cranioplasty to ascertain the safest pin sites.     

Ribbing disease: a case report and literature review

Ribbing disease (RD) is a rare bone dysplasia characterized by benign endosteal and periosteal new bone formation confined to the diaphysis of the long bones of the lower extremities in young adults. The etiology and optimal treatment for the disease are unknown. It is often initially diagnosed as a low-grade osteomyelitis or a bone-forming neoplasia. It may also be confused with other causes of increased bone density. The onset is usually after puberty and the most common presenting symptom is pain that does not resolve with medical treatment and sometimes is intolerable. We report the case of a 22-year old woman with clinical and radiological manifestations of RD. In spite of different medical treatment modalities, pain did not resolve and the patient consulted multiple physicians. Intramedullary reaming of the tibia was performed to relieve the severe pain. To the authors' knowledge, in this report we present a case of RD for the third time in the orthopaedic literature and also she is the second case in the English literature to undergo a definite surgical treatment modality as intramedullary reaming for the solution of her pain. Owing to the rarity of the disease we aimed to report the complete findings of our encounter with the disease and to emphasize the role of an orthopaedic surgeon in consultation and intervention for the treatment of intolerable pain which is the most important symptom of this disease.     

Vancomycin penetration of a brain abscess: case report and review of the literature

A 56-year-old man developed an abscess within a right parietal cystic anaplastic astrocytoma 3 days after removal of iodine-125 sources placed 9 days earlier for interstitial radiation therapy. After treatment with cephalosporin antibiotics proved unsuccessful, the patient was treated with intravenous vancomycin and intermittent percutaneous drainage of the abscess. Vancomycin levels obtained from the brain abscess fluid, both before and during later operative removal of the abscess, were 15 and 18 micrograms/ml, respectively; the serum vancomycin level was 21 micrograms/ml. This is the first report of the excellent penetration of vancomycin into brain abscess fluid.     

Cerebellar abscess due to Rhodococcus equi in an immunocompetent patient: case report and literature review

Rhodococcus equi (R. equi) is a facultative, intracellular, nonmotile, non-spore-forming, gram-positive coccobacillus, primarily causes zoonotic infections that affect grazing animals, mainly horses and foals and is a rare opportunistic pathogen found in severely compromised patients, and most commonly in recent years, in human immunodeficiency virus (HIV)-infected persons. Early cases, most in patients receiving immunosuppressant therapy, were more likely to be successfully treated with antimicrobial agents than cases in AIDS patients, it is emerging as an important pathogen in patients with cellular immune deficiency. We report a case of an immunocompetent 37 year-old patient with cerebellar abscess location that seems to be the only thin to today described in the literature.
