Close examination of a 67-year-old Japanese man, who complained of persistent nocturia, revealed that a semitransparent polypoid tumor had developed from the bladder neck to the prostatic urethra obstructing the internal urethral meatus, which resulted in excessive urinary retention and post-renal dysfunction. The tumor was resected by a transurethral procedure and a pathological examination of specimens revealed aggressive angiomyxoma (AAM) of the prostate. AAM usually develops in the intrapelvic and perineal organs of females. So far as we know, this is the second case of primary prostatic AAM reported in the English literature, and is the first case where the patient encountered urethral obstruction.

Background Urinary retention (UR) is not common in women. There are numerous causes now recognized in women, broadly categorized as infective, pharmacological, neurological, anatomical, myopathic and functional. As opposed to the male, obstructive UR is unusual in women. Methods A 56-year-old woman presented with urinary retention. She reported difficulty in urination for more than 15 days. She had no history of urinary tract infection, bladder surgery and catheterization. Her physical examination revealed a soft tissue mass obstructing the external orifice of the urethra. After its partial removal the patient regained her ability to urinate. Results The patient underwent urological investigation. Ultrasound examination of the urinary system was normal. Cystoscopic examination revealed a papillary lesion with broad base floating along the bladder neck. The patient underwent transurethral resection of the bladder tumor. Discussion Pathological examination diagnosed papillary cystitis. She was scheduled for a regular follow-up with urine cytology, ultrasound and cystoscopy. One year after diagnosis the patient remains free of symptoms and no recurrence was observed. Conclusions Papillary and polypoid cystitis are benign lesions, however under certain circumstances they should be considered in the differential diagnosis of transitional cell carcinoma of the bladder. Lack of the prominent inflammation and edema that characterizes both papillary and polypoid cystitis, and absence of a history of recent bladder catheterization and presence of vesical fistula may facilitate the decision to biopsy the lesion. To our knowledge, this is the first case of papillary cystitis presenting with urinary retention in a woman to be reported in the literature.

We herein present the first case of nanoparticle albumin-bound paclitaxel (nab-paclitaxel)- and/or gemcitabine-induced scleroderma accompanied by acanthosis nigricans-like skin changes in a 54-year-old Japanese male. He was diagnosed with pancreatic cancer and received 17 courses of nab-paclitaxel and gemcitabine chemotherapy. Edema and skin sclerosis in his legs appeared after the first and third course, respectively. Histological examination of the hyperkeratotic lesion of the ankle revealed hyperkeratosis, acanthosis, papillomatosis, increased number of melanocytes in the basal layer, and dermal fibrosis. Awareness of the clinical characteristics of nab-paclitaxel- and/or gemcitabine-induced scleroderma accompanied by acanthosis nigricans-like skin changes is important for dermatologists to establish an accurate diagnosis.

Median raphe cyst is a very rare, benign congenital lesion occurring mainly on the ventral aspect of the penis, but can develop anywhere in the midline between the external urethral meatus and anus. We report a case of median raphe cyst in the perineum presenting as a perianal polyp in a 65-year-old, English white male with exceptionally rare ciliated epithelium. According to our knowledge, this is the third such case of ciliated median raphe cyst in the English literature. This case, also the first case of ciliated median raphe cyst in the perineum location, focuses on pathogenesis of median raphe cyst.

Abstract Imatinib competitively binds to the ATP binding site of Bcr-Abl kinase and inhibits Abl tyrosine kinase activity. Most patients with chronic myeloid leukemia (CML) achieve clinically relevant hematologic and cytogenetic responses to imatinib. It is also a potent inhibitor of a receptor-type c-Kit tyrosine kinase. Therefore, it was examined for therapeutic efficacy against malignant Gastrointestinal Stromal Tumor (GIST), which is a rare tumor of the gastrointestinal tract and is mainly caused by aberrant expression of a mutated c-Kit that is constitutively active without binding of a ligand, stem cell factor. We report two rare cases of double cancer involving CML and GIST. The first case is a 66-year-old Japanese male patient who was presented to our hospital with leukothrombocytosis on February 27, 2006. The patient was diagnosed to be suffering from CML by the presence of Philadelphia chromosome. Several days later, he was admitted with acute peritonitis. A ruptured tumor on 80 cm oral side of ileum end was found by an emergency partial ilectomy. Microscopically, spindle-shaped and round epithelioid cells were growing externally from the intestinal muscular propia. Immunohistochemical analysis showed that the tumor cells were positive for c-kit and CD34 and negative for S-100 protein and desmin. The tumors were identified as GIST. Imatinib was administered to treat CML on the 8th postoperative day. The second case is a 57-year-old Japanese female patient who was presented to our hospital with marked thrombocytosis on March 6, 2006. The patient was diagnosed to be suffering from CML by the presence of Philadelphia chromosome. One year ago, she underwent distal gastrectomy for submucosal tumor. Pathological examination revealed proliferation of submucosal spindle-shaped cells with elongated cigar-shaped nuclei arranged in fascicles. Immunohistochemical stains confirmed the diagnosis of GIST. These two cases provided a valuable opportunity for treating GIST with CML. We look forward to active effect of imatinib, not only in CML treatment but also in preventing recurrence of GIST. The occurrence mechanism of either CML or GIST at the biomolecular level has been established. However, we can show no relation between these malignancies. Therefore, it is natural for us to understand accidental coincidence. We should follow-up these patients carefully. Accumulation of such cases may contribute to clarify more precise mechanism of tumorgenesis.

Abstract Background Cronobacter sakazakii (C. sakazakii) is a bacterium known to cause severe neonatal infections in premature infants with the consumption of contaminated powdered milk formula. Adult infections are rare, and there have been no reports of pyosalpinx due to C. sakazakii to date. Case presentation We report a case of left pyosalpinx due to C. sakazakii in a sexually inactive postmenopausal woman. A 70-year-old woman presented to our hospital with left lower abdominal pain and fever. Abdominal computed tomography disclosed a cystic mass continuous with the left edge of the uterus. Urgent laparotomy revealed a ruptured left pyosalpinx with pus-like content. Left salpingo-oophorectomy, resection of the right tube, and washing of the abdominal cavity with saline were performed. Pathological examination of the left adnexa showed tubal tissue with acute inflammation and inflammatory exudate, which were compatible with pyosalpinx, and pus culture yielded C. sakazakii. Conclusions This is the first case report of pyosalpinx due to C. sakazakii. Cronobacter sakazakii infections in adult women might occur in the elderly, whose immunity has weakened. Further accumulation of cases of C. sakazakii infection is needed to clarify the etiology and behavior of C. sakazakii in adults.

AbstractA 78-year-old Japanese male with Clostridium perfringens septicemia and cholecystitis was found to have thrombosis in the left branch of intrahepatic portal vein as well as superior mesenteric vein. Visceral vein thrombosis (VVT) in this case was associated with protein C deficiency, due to a heterozygous mutation, p. Arg185Met. Our experience emphasizes that VVT, or other thromboembolic events, may occur in later life, triggered by environmental thrombosis risk factors, together with underlying hereditary protein C gene mutation.

A 23-year-old female was involved in a motor vehicle collision with multiple injuries, including a right acetabular fracture, but no pelvic fracture. Urology consultation was obtained due to difficulty placing a urethral catheter. Examination revealed a longitudinal urethral tear with vaginal laceration extending 2 cm from the urethral meatus proximally toward the bladder neck. The longitudinal urethral tear was repaired primarily. Traumatic female urethral injury in the absence of a pelvic fracture is an exceedingly rare occurrence.

Abstract Background: Since the discovery of the first case of Anaplastic lymphoma kinase (ALK) -positive histiocytosis in 2008, originally described as a systemic, self-limiting disease in infants, the range of ALK-positive histiocytosis has recently been expanded to include localized diseases in older children and young adults. Case presentation: We present the case of an 18-year-old female with periumbilical painless mass for 5 months, who underwent a resection of the mass. Pathological examination showed the tumor consists predominantly of fascicular to storiform growth of nonatypical spindle cells, admixed with lymphocytic infiltrates. The tumor spindle cells were diffusely positive for CD68, CD163 and ALK. Further, molecular tests revealed ALK gene fusion: Kinesin Family Member 5B (KIF5B) (E24)-ALK (E20), confirmed ALK-positive histiocytosis. The tumor has not recurred one and a half years after resection by follow-up examination.Conclusion: ALK-positive histiocytosis in local lesion can achieve remission by complete resection and clinical follow-up showed a favorable prognosis.

Macracanthorhynchus Hirudinaceus

Sanitary management and population control of feral pigs remains a major problem in public health, particularly in natural parks where hunting is prohibited and the extensive farming of livestock is common. Macracanthorhynchus hirudinaceus is a zoonotic parasite species with a worldwide distribution of which the natural definitive hosts are primarily pigs and wild boars (Sus scrofa). The present study describes the main anatomo-pathological and parasitological findings in the first case of M. hirudinaceus in feral pigs in the Madonie park in Sicily (Southern Italy). Overall, 52 acanthocephalans were collected from the small intestine of four infected feral pigs. The prevalence among the 36 examined animals was 11.1% with a mean Abundance (mA) and mean Intensity (mI) of 1.4 and 13, respectively. Pathological examination revealed grossly visible nodules on the external surface of the intestines, corresponding to the proboscis of M. hirudinaceus attached deeply into the intestinal wall. In these sites, severe inflammatory reactions in the tissue involved and the destruction of normal intestinal architecture, as well as necrosis and ulceration in the mucosa, submucosa, and part of the muscolaris mucosae were described. This is the first official report of this neglected zoonosis in Italy, in particular in a natural park where the extensive farming of domestic pigs is practiced. This could favor the spread of this parasite in domestic animals and the environment, increasing the accidental risk of infection in human residents of these areas.
