Abstract :Background : Generally speaking, urethral malignancies are uncommon urological tumors that are more frequent in women than in men. The etiology of female urethral adenocarcinoma is yet unknown, however it is an uncommon disorder. Recurrent UTIs and urethral diverticula are two common risk factors linked to it, though. Clinical presentations can differ and are not always specific. A complete history and physical examination are part of management; urethrocystoscopy with urethral biopsy is used for diagnosis; investigations such as magnetic resonance imaging or abdominal computed tomography scans are used for staging; and treatment options include monotherapy and multimodal therapy.Case Presentation: A 53-year-old female who presented with a nine-month history of lower urinary tract symptoms characterized by burning sensation when passing urine, increased urinary frequency, and feeling of incomplete bladder emptying associated with feeling of a vaginal mass. She was being managed for recurrent urinary tract symptoms at another facility. Examination revealed fungating fixed mass at the external urethral orifice. Pelvic magnetic resonance imaging reported a retropubic urethral mass with bilateral inguinal lymph nodes, and she underwent urethrocystoscopy with multiple urethral biopsies taken, and the specimen was sent for histopathology biopsy, which confirmed a well-differentiated urethral adenocarcinoma with mucin production, and she was treated with chemo-radiotherapy as per multidisciplinary team meeting recommendation. She developed symptoms of radiation proctitis, which was treated with argon plasma coagulation. She has since been on follow-up at our oncology clinic, and a subsequent Positron Emission Tomography CT scan reported no tumor recurrence or metastasis. She is currently faring well with no recurrence of her symptoms, and wounds have healed.Conclusion: Although female urethral adenocarcinoma is uncommon, it nevertheless requires a comprehensive investigation when it is suspected, particularly in women who have nonspecific or recurrent lower urinary tract symptoms. Management can involve a multidisciplinary team approach where available. Depending on the disease’s stage and location, treatment options may include surgery, nonsurgical such as radiotherapy and chemotherapy, or a combination. Patients should be monitored for any signs of recurrence of the illness. A better prognosis is said to exist for distal urethral cancers that are localized.

Introduction.Pyelonephritis is an inflammation of the renal parenchyma primarily due to bacterial infections9. Chronic pyelonephritis can result in an unusual form of a disease known as Xanthogranulomatous pyelonephritis (XGP)9. Patients with this disease usually present with a chronic urinary tract obstruction due to an underlying renal calculus and urinary tract infections9. The most frequent organisms extracted from XGP patients are Escherichia coli (E. coli) and Proteus mirabilis, with different levels of antimicrobial resistance being presented2.XGP is marked by extensive damage to renal parenchyma which is then substituted by a focal collection of Xanthomatous mass of lipid-laden macrophages also known as foam cells 1, however, the exact etiology of XGP is still unknown. The disease is very rare, its incidence in the general population is 1.4 cases per 100,000 population each year 4. The highest incidence is at 50 to 70 years of age, with a female predominance. The most common clinical manifestation of XGP includes anemia, excessive weight loss, abdominal or frank pain, palpable frank mass, and fever 3.There is usually a challenge in establishing a correct diagnosis of XGP, this is because it mimics other renal pathologies 1. XGP has acquired the nickname of the “great imitator “, due to the matching of the radiological characteristics of other pathologies including renal cell carcinoma (RCC), Malakoplakia, Tuberculosis (TB), and urothelial tumors (TCC) 2.Management of XGP involves a combination of both medical and surgical approaches. A retrospective study was conducted to report the outcomes of XGP patients who underwent nephrectomy in their institution for over 12 years. Bacteriuria was found in most of the patients (91%), with Escherichia coli (E. coli) being the predominant organism. 60% of positive urine samples had antibiotic resistance. All patients underwent open nephrectomy except for one. It was concluded that open nephrectomy is often required in complicated cases of XGP, and it is associated with high rates of postoperative complications, however meticulous contemplation of antibiotics and surgical interventions is important to ensure the effective outcome of the patients 2. Here we share a rare case of a female with XGP.

INTRODUCTIONPyoderma gangrenosum (PG) is a rare, primary sterile, inflammatory, non-infective, and non-malignancy skin disease that is classified into four variants (ulcerative, pustular, bullous, and vegetative) (Table 1). Up to 50% of PG cases might have systemic diseases such as hematological malignancy, rheumatoid arthritis, paraproteinemia, myeloproliferative disorder, and inflamatory bowel diseases such as Crohn’s disease and ulcerative colitis. It’s found that up to 5% of cases of PG have ulcerative colitis and 1.5% have Crohn’s disease (1), (2), (3), (4), (5). In the 1930s, Brunsting et al. were the first to define PG as a disease entity. They described it in five patients who presented with large, painful necrotic ulcers with undermined borders of bluish coloration enclosed by regions of erythema. In those five patients, four had ulcerative colitis. The cause is still unknown, though it was hypothetically thought to be a bacterial disease and sometimes a cutaneous manifestation of inflammatory bowel disease, which has been refuted by current studies (2).The incidence of PG annually in the United States is estimated to be 1 case in 100,000, while the worldwide incidence is between 3 and 10 million. General PG is a diagnosis of exclusion, with penile conditions having considerable differentials, including infections such as syphilis, amoebiasis, herpes simplex, mycobacterial ulceration, and non-infectious origins of venereal ulceration like cutaneous Crohn’s disease, squamous cell carcinoma, and ulcerating sarcoidosis. It should be considered in lesions where antimicrobial or antiviral therapy has not responded or for the non-confirmatory diagnosis of skin conditions (6). Frequently, PG occurs between the ages of 25 and 54, though it might occur at any age. It is extremely rare in pediatrics; 4% of cases have been reported in pediatrics and infants; in infants alone, 8.8% of all pediatric cases are reported. The youngest reported case is 3 weeks old. Females are more affected than males, and their peak age is in their third and fourth decades, while their counterpart males are in their fifth decade. The initial lesion is a tender pustule, whereas in infants, the areas involved are perianal and genital, and in children, the lesions involve the head, face, and gluteal areas (4).Typically, PG lesions start as small vesiculopustular, which progresses to an ulcer with violaceous overhanging borders, and these occur mostly in the lower extremities, though not limited to other organs. In this typical form, it is believed that if the condition is associated with arthritis, they become more refractory to treatment than those without arthritis. Atypical forms are clinically presented as superficial lesions with blue-gray bullous borders involving the extremities, head, and neck. Regardless of the presence of other systemic conditions, it can be acute or chronic. A PG patient presents with a condition called pathergy, which is the development of a lesion at a site of trauma, whether it be iatrogenic, animal bites, or any injury, and it is due to hyper-reactivity of the skin (8). Apart from PG, other conditions that may present with pathology are sweet syndrome, blindloop syndrome, erythema elevatum diutinum, and Behcet’s disease. Pathergy should not be confused with the Koebner/isomormorphic response, which is the formation of new skin lesions in areas that were not involved in trauma. 10–30% of PG reported cases are idiopathic; 20% of patients will present with a Koebner response, while 20–30% will present with pathology (9, 10).
