    Abstract Background: Little information is available on male breast cancer (MBC) incidence from sub-Saharan Africa.
    Objective: This is a retrospective study on MBC in rural North Uganda, based on the pathology records of a private, non-profit, missionary hospital.
    Methods: All male patients that had histological diagnosis of breast carcinoma from January 2009 to December 2016 were included in this study.
    Results: In time span of 8 years, there were 337 consecutive breast cancer presentations, including 21 MBC (6.2%). The latter patients showed advanced disease (mean symptom duration: 20.3 months; mean tumour size: 5 cm) skin ulceration and ipsilateral lymph node metastasis: 60%). The mean age was 60.52 years (from 30 to 85 yrs). Ductal infiltrating carcinoma was the prevalent histological type in our series (65%), followed by an unusually high rate of papillary carcinomas (15%). There appeared to be a prevalence for left breasts (11 LT versus 6 RT; 64.7%), a finding also observed in the majority of MBC.
    Conclusions: This study is representative of the scenario in Northern Uganda, where MBC accounts for 6.2% of breast cancers, More information on the occurrence and risk factors of this unusual neoplasm in African countries may prompt prevention of chronic liver disease and early recognition and treatment of MBC.

    Abstract Purpose: Gastric infection with Strongyloides stercoralis (SS) usually occurs in immunocompromised patients. The unexpected observation of this parasite in an otherwise healthy young lady who had undergone upper endoscopy and biopsy sampling of the gastro-duodenal mucosa, prompted us to review the literature to ascertain the conditions favouring gastric colonization by SS.
    Methods: Pathology files of gastroduodenal biopsies received at St. Mary's hospital, Northern Uganda, between 2007 and 2017 were reviewed. Pubmed search was performed under the headings "Strongyloides stercoralis", "Gastric parasitosis".
    Results: Histology of the only gastroduodenal biopsy with SS infection showed parasite eggs, immature rhabditiform larvae, and numerous adult worms in gastric pits and rhabditiform larvae in interepithelial parasitic tunnels, causing reactive changes of the glandular epithelium. There was no significant acute inflammatory cell infiltrate surrounding the parasites. Literature review showed that gastric SS infection appears to be very uncommon and was, as expected, largely prevalent in immunodeficient individuals (84.2% of published cases). The rare gastric SS infection is a complication of systemic strongyloidiasis, either hyperinfective, or disseminated form. It is also commonly associated with duodenal infection at microscopical examination.
    Conclusion: Involvement of gastric mucosa in the absence of duodenal strongyloidiasis appears to be quite rare and false-negative histopathological exams are reported if only the stomach is biopsied.

    Abstract Ciliated epithelial cells have been rarely observed in urothelium lined mucosa. Only extremely rare reports in the literature have described this phenomenon and no cases have been described in other sites than the male urethra. Herein, we illustrate the finding of ciliated pseudostratified columnar cells in the renal calyx mucosa adjacent to an area of urothelial invasive carcinoma in an 82 year-old man with previous history of nephrolithiasis. The ciliated cells covered a linear extension of 0.5 cm: they were positive for keratin 7 and keratin 8/18 and negative for keratin 20. Alcian blue staining was positive in some vacuoles in the apical cytoplasm of the same cells whereas PAS (Periodic Acid-Schiff) staining was negative. GATA3 resulted negative in ciliated cells except for a layer in the basal portion of the epithelium, just above the basal membrane. The actual prevalence of ciliated epithelia in the urinary tract is not well documented and the current knowledge on the subject is limited to electron scanning microscopy studies. The significance of this phenomenon remains unknown: it could be either a developmental abnormality or more probably a metaplastic change. Associated urolithiasis, which has been described in both a previous report and in the present one, could hypothetically represent a possible trigger for this unusual cell change. However, this hypothesis needs to be confirmed through further investigation.

    Abstract Lymphomas presenting and mimicking soft-tissue masses are important to recognize, to avoid unnecessary treatment delays or extensive surgery. We describe a case of primary anaplastic large cell lymphoma (ALCL) arising from a deep skeletal muscle in a middle-aged male. He presented with a two-month history of swelling of his right thigh and mild fever, which led to a diagnosis of abscess formation. Antibiotics were prescribed for two weeks, with little improvement of symptoms. Subsequently, an exploratory surgery, with excision of the mass, demonstrated a ALCL of the psoas muscle, ALK-1 positive.

    Abstract Permanent ischemia-induced testicular damage may occur as early as 30 min in prepupertal rats. With the goal of potentially enhancing testicular function and fertility preservation, we performed testis-sparing surgery (TSS) without ischemia for testicular lesions in select children with negative markers and high likelihood of benignity on ultrasonography. Preliminary experience suggests that off-clamp TSS should be more liberally encouraged, especially in infants and prepubertal children, given their particularly vulnerable spermatic cord elements.

    Abstract Purpose: Prostatic tissue in an ovarian teratoma is an unusual finding, whose initiation in a 46, XX karyotype tissue is yet to be clarified. We present a case from our files and review the literature for this intriguing finding.
    Methods: Unstained histology sections of the ovarian teratoma containing prostatic tissue were evaluated using immunohistochemistry for PSA and androgen receptor.
    Results: Both PSA and androgen receptor immunostainings were positive in the prostatic tissue. From the literature review, it appears that most of the patients (74%) with similar findings were either pregnant or experiencing a miscarriage, menopausal or infertile at presentation, showing that an imbalanced hormone status is frequently associated with the presence of male structures in ovarian teratomas.

    Abstract We performed next generation sequencing of DNA extracted from the neoplastic tissues obtained from a patient who underwent surgery for a large right ovarian carcinoma (OC) of endometrioid type associated with endometrial cancer (EC). This was done in order to ascertain whether the tumors were synchronous endometrial/ovarian cancers or an advanced metastatic stage from either the ovary or the uterus. Pathologic criteria favoured synchronous EC/OC. We identified a PTEN c.959 T > G (p.L320X) truncating mutation occurring with similar allele frequency in both neoplastic tissues (ovary: 88 %, endometrium 89 %) and a CTNNB1 c.100C > G (p.S37C) activating mutation, with a comparable allelic frequency in both tumor tissues (ovary 51 %, endometrium 52 %). The shared genetic mutations, and the presence of PTEN c.959 T > G (p.L320X) truncating mutation, albeit at low allelic frequency (6 %), in the healthy peritumoral endometrial tissue, appear to confirm the recent literature on a primary endometrial origin for synchronous EC/OC. A third mutation was CTNNB1 c.92 T > C (p.L31 P), a missense mutation occurring with a low allele frequency (3.7 %) only in the ovarian cancer tissue. This mutation is only occasionally described in hepatocellular carcinomas.

    Abstract This report documents an uncommon case of choristomatous cervical polyp-containing fat tissue. The patient was a 24-year-old female who presented with irregular intermenstrual bleeding. On examination, a polypoid lesion with smooth outlines, measuring 1 cm in diameter was removed. Microscopic examination demonstrated abnormal fibrous stroma, devoid of endocervical glands, containing mature adipose tissue, and thick-walled blood vessels. The lesion was covered by a typical mature squamous cell outer lining. To the best of our knowledge, this is only the second report of an adipose tissue arising from the cervical wall. Further clinicopathologic considerations are needed to elucidate the origin of the fatty component in cervical polyps.

    Abstract Purpose: The purpose of this study was to evaluate in vivo the role of the micro-balloon by comparing trans-arterial chemoembolization (DEB-TACE) and selective internal radiotherapy (SIRT) procedures performed with and without balloon micro-catheter (b-DEB-TACE and DEB-TACE/SIRT and b-SIRT) for the treatment of hepatocellular carcinoma (HCC).
    Methods: The impact of a balloon micro-catheter on trans-arterial loco-regional treatment was analyzed using non-enhanced post-procedural cone-beam CT (Ne-CBCT) by comparing the attenuation values in the embolized area and the surrounding liver tissue before and after DEB-TACE versus b-DEB-TACE and by comparing 2D/3D dosimetry in single-photon emission computed tomography after SIRT versus b-SIRT, and by comparing the histological count of the beads following orthotopic liver transplantation in the DEB-TACE versus b-DEB-TACE subgroup.
    Results: We treated 84 HCC patients using trans-arterial loco-regional therapy. Fifty-three patients (26 DEB-TACE and 27 b-DEB-TACE) were analyzed in the TACE group. Contrast, signal-to-noise ratio, and contrast-to-noise ratio were all significantly higher in b-DEB-TACE subgroup than DEB-TACE (182.33 HU [CI95% 160.3-273.5] vs. 124 HU [CI95% 80.6-163.6]; 8.3 [CI95% 5.7-10.1] vs. 4.5 [CI95% 3.7-6.0]; 6.9 [CI95% 4.3-7.8] vs. 3.1 [CI95% 2.2-5.0] p < 0.05). Thirty-one patients (24 SIRT and 7 b-SIRT) were analyzed in the SIRT group. 2D dosimetry profile evaluation showed an activity intensity peak significantly higher in the b-SIRT than in the SIRT subgroup (987.5 ± 393.8 vs. 567.7 ± 302.2, p = 0.005). Regarding 3D dose analysis, the mean dose administered to the treated lesions was significantly higher in the b-SIRT than in the SIRT group (151.6 Gy ± 53.2 vs. 100.1 Gy ± 43.4, p = 0.01). In histological explanted liver analysis, there was a trend for higher intra-tumoral localization of embolic microspheres for b-DEB-TACE in comparison with DEB-TACE.
    Conclusions: Due to the use of three different methods, the results of this study demonstrate in vivo, a better embolization profile of oncological intra-arterial interventions performed with balloon micro-catheter regardless of the embolic agent employed.
