Abdominal-pelvic actinomycosis is often mistaken for other conditions, presenting a preoperative diagnostic challenge. In a 46-year-old female, computed tomography showed an abdominal-pelvic retroperitoneal mass extending from the lower pole of the right kidney to the lower pelvis. The patient had a 3-year history of intrauterine device. The mass appeared to involve the ascending colon, cecum, distal ileum, right Fallopian tube and ovary, and ureter anteriorly and the psoas muscle posteriorly. The resection of retroperitoneal mass, distal ileum appendicectomy, right hemicolectomy, and right salpingo-oophorectomy was performed. The postoperative period was uneventful. Penicillin therapy was given for six months without any complication. The retroperitoneal mass measured 4.5 × 3.5 × 3 cm, surrounded adjacent organs and histologically showed inflammatory granulomatous tissue, agglomeration of filaments, and sulfur granules ofActinomyces, with positive reaction with periodic acid Schiff. Right tubo-ovarian abscess was present. Abdominalpelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intrauterine device.

Actinomycosis is an underreported chronic invasive disease caused by Actinomyces spp. In that group of diseases, pelvic actinomycosis is very rare and most of the cases reported in the literature have shown unilateral psoas muscle involvement. We report a 35-year-old woman with a retroperitoneal mass located in the left psoas muscle that makes abdominal tenderness and difficulty in walking. She had a 7-year history of intrauterine device which had been removed one month just before this event. After undergoing two laparotomies to perform a biopsy with undetermined results, she developed a new mass in the right psoas muscle which was similar to the left one. On the third attempt, the histopathology revealed yellow sulfur granules of Actinomyces which reacted positively with periodic acid Schiff and Grocott’s dye. After three months of treatment with Amoxicillin plus Clavulanic acid, her abscesses were completely resolved. Actinomycosis should always be included in the diagnostic list in patients with a pelvic mass and a history of intrauterine device.

AbstractAsymptomatic female genital tract colonization with Actinomyces spp is not uncommon, particularly among intrauterine device users. Pelvic actinomycosis is an extremely rare disease. The clinical picture can resemble an advanced ovarian malignancy. We report a case of pelvic actinomycosis mimicking ovarian malignancy diagnosed postoperatively. Preoperative diagnosis is possible if there is a high index of suspicion, obviating extensive surgery and preserving fertility, since long term antibiotic treatment can be completely effective. Pelvic actinomycosis should be included in the differential diagnosis of women presenting a pelvic mass, especially if there is intrauterine device use history.

In women, pelvic actinomycosis is closely associated with prolonged use of the intrauterine devices (IUD). A 70-year old female presented with intermittent blood-stained vaginal discharge. An analysis of her history revealed, she was inserted with an IUD 42 years ago, but it has remained in situ untill now. Curettage of the uterus was done, but an IUD was firmly attached inside the cavity and there was not able to remove it. A biopsy material consisted of the large round and oval granules of filamentous and mycelium-like microorganisms. They showed strong positivity with Periodic acid–Schiff stain and Gömöri methenamine silver stain. Histopathology was consisted with uterine actinomycosis. A total abdominal hysterectomy with bilateral adnexectomy was performed. The uterus contained a retained plastic IUD. Microscopic investigation revealed a diffuse chronic active endomyometritis with sporadic Actinomycetes colonies. Wearing an IUD continuously for very long periods of time can lead to actinomycotic infection, which may manifest for many years after its application. All IUD users have to keep in mind regular gynecological check-ups to avoid the complications of a retained and “forgotten” IUD.

Actinomycosis is a chronic bacterial infection characterized by continuous local spread, irrespective of anatomical barriers, and granulomatous suppurative inflammation. Due to its expansive local growth, it can simulate a malignant tumour. Subsequent hematogenous dissemination to distant organs can mimic metastases and further increase suspicion for malignancy. A case of severe disseminated pelvic actinomycosis associated with intrauterine device is described here. The patient presented with a pelvic mass mimicking a tumour, bilateral ureteral obstruction, ascites, multinodular involvement of the liver, lungs and spleen, inferior vena cava thrombosis and extreme cachexia. Actinomycosis was diagnosed by liver biopsy and confirmed by culture of Actinomyces naeslundii from extracted intrauterine contraceptive device (IUD). Prolonged treatment with aminopenicillin and surgery resulted in recovery with moderate sequelae.

Background: Granulomatous dermatosis shares the histological finding of granuloma formation; it is usually formed because of the persistence of a non-degradable product of active hypersensitivity. The identical histological picture may be produced by several causes, which pose a diagnostic challenge to dermatopathologist, Present study aims at classifying cutaneous granulomatous dermatosis based on the morphology and aetiology of granulomas, and to highlight its significance for specific clinical diagnosis.Methods: A retrospective analysis of skin biopsy was done and cases of cutaneous granulomatous lesions diagnosed on histopathological examination were retrieved for a period of 8 years. Clinical data and diagnosis were retrieved from hospital records. Hematoxylin and eosin stained paraffin sections were reviewed. The morphological pattern of granuloma was classified into sarcoidal, necrotizing, necrobiotic and suppurative granulomas and further aetiological evaluation for the granulomatous dermatosis were done using various special stains like Periodic Acid Schiff stain, Fite-Farraco stain, Gomori methenamine silver stain and acid-fast bacilli stain.Results: A total of 228 cases of cutaneous granulomatous lesion were retrieved; out of these 93cases (40.79%) were sarcoidal granuloma type, 83cases (36.40%) were of suppurative granulomas, 29 cases (12.72%) were of necrobiotic granulomas, 20 cases (8.77%) were necrotizing granuloma and 3 cases (1.32%) had granulomatous dermatitis with vasculitis. Infective aetiology was the commonest cause for granulomatous dermatosis (57.89%), mainly by leprosy, tuberculosis and various fungal infection.Conclusions: Granulomatous dermatosis has significant overlap in histopathological picture of various granulomatous reactions. Morphology alone is seldom specific and cannot be used as diagnostic tool. It is better understood based adequate clinical data, morphology of granuloma, special stains and laboratory workup in arriving at a etiology specific diagnosis for definitive clinical management.

Pelvic and intra-abdominal Actinomycosis can be difficult to diagnose preoperatively and it may also mimic many other diseases, including malignancies. We present a patient with pelvic Actinomycosis probably caused by a long-standing intrauterine device (IUD). We emphasize the challenges in diagnostic process and stress that though a rare disease, intra-abdominal Actinomycosis should be suspected in cases with intra-abdominal mass of uncertain etiology. The early recognition may spare the patient from extensive surgical operation.

e22542 Background: Retroperitoneal lipo-leiomyomata are extremely rare. The usual-type retroperitoneal leiomyoma is itself a rare tumor that is mistaken preoperatively for malignant retroperitoneal tumors or thought of as an exophytic subserosal leiomyoma of the uterus. Lipo-leiomyoma is a variant of leiomyoma with an incidence in uterus ranging between 0.03% - 0.2%, but its presentation as a retroperitoneal mass has not been documented in literature yet. We present a unique case of retroperitoneal lipo-leiomyoma that presented as a diagnostic challenge due to its unique location and unusual histologic appearance. Methods: A 68-year-old female patient with a history of breast cancer diagnosed 4 years ago, currently on antiestrogen therapy (Fulvestrant) and Herceptin, presented to our university hospital with symptomatic left pelvic mass. An abdominal CT showed a heterogeneous low-density pelvic mass with foci of internal calcification and fat with surrounding intermixed intermediate and high density fluid in the expected location of the uterus. Results: A debulking surgery including radical hysterectomy was planned. Intraoperatively, a normal sized uterus was found, the myometrium of which contained multiple variable-sized intramural leiomyomata. In addition, a huge left retroperitoneal mass was found that had no connection to the uterus. Histopathological examination revealed abenign lipoleiomyomatous tumor, composed of an encapsulated proliferation of benign adipocytes and myoid cells intimately admixed. Immunohistochemistry confirmed myoid differentiation, with negative reactions for HMB45 and CKIT, and . MDM2 gene amplification by fluorescence in situ hybridization (FISH) was negative. Conclusions: Some unusually located extra-uterine leiomyomata have been reported; retroperitoneal leiomyoma being among them. Such a tumor with the added feature of lipomatous differentiation presents a differential diagnosis that includes leiomyosarcoma, liposarcoma, angiomyolipoma, and gastrointestinal stromal tumor. The association of an uncommonly located leiomyoma with subsequent lipomatous change withantiestrogen therapy is an unexplored issue that merits further investigation.

Parotid glands were obtained from five adult (four male and one female) armadillos (Dasypus novemcinctus) which were perfusion-fixed. The glands were located in a position similar to that of most mammals. They extended interiorly to the anterior portion of the submandibular gland.In the light microscope, it was noted that the acini were relatively small and stained strongly positive with the periodic acid-Schiff (PAS) and alcian blue techniques, confirming the earlier results of Shackleford (1). Based on these qualities and other structural criteria, these cells have been classified as seromucous (2). The duct system was well developed. There were numerous intercalated ducts and intralobular striated ducts. The striated duct cells contained large amounts of PAS-positive substance.Thin sections revealed that the acinar cells were pyramidal in shape and contained a basally placed, slightly flattened nucleus (Fig. 1). The rough endoplasmic reticulum was also at the base of the cell.

SummaryQuantitative glycoprotein (GP) analysis of whole platelets or platelet membranes was performed by SDS-polyacrylamide gelelectrophoresis (SDS-PAGE) and periodic acid Schiff staining in the families of two unrelated Glanzmann’s thrombasthenia (GT) patients. Each family consisted of two symptom free parents, a symptom free daughter and a GT daughter. All symptom free members had a normal bleeding time, clot retraction and platelet aggregation response to adenosine 5’-diphosphate (ADP), collagen and adrenalin. Platelet Zw* antigen was normally expressed in these subjects. GT patiens, classified as a type I and II subject, showed reduced amounts of GP lib and of GP nia. Analysis of isolated membranes in the non-reduced state, however, showed that the amount of GP Ilia was also reduced in three of the four parents, whereas one parent (of the GT type I patient) and the two unaffected daughters had normal amounts of GP Ilia. Quantitative SDS-PAGE may therefore provide a method for the detection of asymptomatic carriers in GT type I and II.

In this study, spontaneous swim bladder mycosis was documented in a farmed fingerling rainbow trout from a raceway culture system. At necropsy, the gross lesions included a thickened swim bladder wall, and the posterior portion of the swim bladder was enlarged due to massive hyperplasia of muscle. A microscopic wet mount examination of the swim bladder contents revealed abundant septate hyphae, and histopathological examination showed periodic acid-Schiff-positive mycelia in the lumen and wall of the swim bladder. Histopathological examination of the thickened posterior swim bladder revealed muscle hyperplasia with expansion by inflammatory cells. The causative agent was identified as Phoma herbarum through morphological analysis and DNA sequencing. The disease was reproduced in rainbow trout fingerlings using intraperitoneal injection of a spore suspension. Necropsy in dead and moribund fish revealed extensive congestion and haemorrhages in the serosa of visceral organs and in liver and abdominal serosanguinous fluid. Histopathological examination showed severe hepatic congestion, sinusoidal dilatation, Kupffer cell reactivity, leukostasis and degenerative changes. Fungi were disseminated to the liver, pyloric caeca, kidney, spleen and heart. Although infections caused by Phoma spp. have been repeatedly reported in fish, species identification has been hampered by extensive taxonomic changes. The results of this study confirmed the pathogenicity of P. herbarum in salmonids by using a reliably identified strain during experimental fish infection and provides new knowledge regarding the course of infection.
