Prostate carcinoma mimicking rectal cancer: a case report.

In the pre-prostate specific antigen era, patients with prostate cancer (PC) commonly presented with symptoms. Currently, most PC are diagnosed at an asymptomatic stage with abnormal digital rectal examination or raised prostate specific antigen. In rare cases, PC may infiltrate the rectum and cause symptoms mimicking rectal cancer. It is difficult to differentiate between the two based on clinical features alone. We here report our experience in managing an 86-year-old male, with no significant personal pathological history, who presented with diarrhea and occasional rectal bleeding without any lower urinary tract symptoms. Investigations concluded to a PC invading the rectum and the patient was referred to urology department.

Cholesterol Granuloma of the Breast Mimicking Cancer: A Case Report and Review of the Literature.

Cholesterol granuloma of the breast is an infrequent benign lesion with clinical and radiological findings suggestive of cancer. Herein, we present the case of a 52-year-old woman with no significant past medical history, who presented to the outpatient department for her routine breast screening. Physical examination revealed a painless palpable nodule in the upper external quadrant of the left breast, measuring 0.7 cm. On imaging, the mass met the criteria for Breast Imaging Reporting and Data System (BI-RADS) category 4B. Subsequently, a core needle biopsy of the mass was performed. Despite the alarming radiologic features, microscopic findings were consistent with breast cholesterol granuloma.

A case report of testicular diffuse large B-cell malignant lymphoma with cutaneous metastasis: A rare entity.

INTRODUCTION AND IMPORTANCE: Primary testicular lymphoma (PTL) is a variety of extra-nodal lymphoma taking origin from testis. It accounts 5% of all testicular tumors. Metastasis may occur in contralateral testis, bone, central nervous system and rarely in skin. Herein, we present the case of testicular diffuse large B-cell malignant lymphoma with cutaneous metastasis. CASE PRESENTATION: A 60-year-old male presented with swollen painless solid right testis, with homolateral inguinal nodes. Testicular tumors markers were within normal range. Right radical orchidectomy was performed. Histopathological examination concluded to the diagnosis of Diffuse Large B Cell Lymphoma. Four weeks later, the patient presented alteration of general condition and multiples cutaneous centimetric lesions located in the right inguinal region. Biopsy of this lesion confirmed the diagnosis of metastases from the testicular lymphoma. The patient deceased three days later, before starting further treatment. CLINICAL DISCUSSION: Primary testicular lymphoma is a rare variety of testicular tumors. The prognosis is poor. Metastasis may occur in different sites such as contralateral testis, central nervous system, and skin. The prognosis is usually poor in the rare case of cutaneous metastasis. CONCLUSION: Primary testicular tumor is an aggressive rare variety of testicular tumors with poor prognosis. Cutaneous metastasis is rarely reported. Cutaneous lesions should be explored and suspected to be malignant. Early treatment with rapid multidisciplinary management is the key for adequate approach.

An unusual association of adenocarcinoma and isolated tuberculosis of prostate gland.

Adenocarcinoma of prostate is the most common primary prostatic malignancy in the world. Isolated prostate tuberculosis is an uncommon type of tuberculosis. Concomitant occurrence of both conditions is extremely rare. We report two cases of adenocarcinoma and tuberculosis of the prostate. The patients were 83 and 74 years old, respectively. They presented obstructive and irritative symptoms of the lower urinary tract. The prostatic finding and prostate-specific antigen were abnormals. The diagnosis of prostatic tuberculosis and adenocarcinoma was made by histologic analysis after transurethral resection of prostate. The treatment is based on chemotherapy anti-tuberculosis and hormonotherapy. Tuberculosis and malignancy may co-exist in some cases and clinicians must have a high index of suspicion for tuberculosis, especially in patients from endemic areas, in order to initiate early and proper treatment.

Spontaneous bladder diverticulum rupture due to a squamous cell carcinoma of the bladder: a case report.

While bladder rupture is most of the time secondary to external injury such as trauma or iatrogenic events, spontaneous bladder rupture (SBR) is a rare condition which is mostly associated with bladder cancer, neurologic bladder or radiotherapy. We report a case of a 63-year-old patient with an invasive squamous cell bladder carcinoma who presented acute peritonitis caused by a SBR while being prepared for radical surgery. CT-scan helped to confirm diagnosis and emergency cystectomy was performed. SBR should be considered in differential diagnosis of peritonitis. On time diagnosis and adequate surgery could improve its prognosis.

HHV8/EBV Coinfection Lymphoproliferative Disorder: Rare Entity with a Favorable Outcome.

HHV8/EBV-associated germinotropic lymphoproliferative disorder (GLD) is a challenging diagnosis given its rarity, the particular clinical presentation, and the lack of expression of markers usually used in establishing hematopoietic lineage. We report a new case of HHV8/EBV GLD in an immunocompetent 78-year-old woman. The diagnosis was made in an incidentally discovered lymphadenopathy. Histological examination showed a nodular lymphoid proliferation centered by aggregates of atypical plasmablastic cells admixed with small lymphoid cells. Tumor cells were strongly positive with EMA, HHV8, LMP1, CD38, CD138, and kappa light chains. They were negative with common lymphoma-associated markers (CD20, CD3, CD15, CD30, CD10, and bcl2). In situ hybridization confirmed the monotypic kappa light chains and the EBV infection (EBER+). A polyclonal pattern of Ig gene rearrangement was detected by PCR analysis. In the adjacent lymph node parenchyma, some germinal centers mimicked Castleman disease. In this case, the differential diagnosis was discussed with an early stage of large B-cell lymphoma arising in HHV8-associated multicentric Castleman disease. The clinical presentation, the immunophenotype, and the molecular results helped to make the accurate diagnosis. Through the review of the nine previously reported cases in literature, we discuss the clinical and pathologic features and the differential diagnosis of HHV8/EBV GLD.
