Bladder metastasis from inflammatory breast cancer presenting with hematuria and hydronephrosis.

We report a rare case of a 56-year-old Ukrainian female with inflammatory breast cancer (IBC) who underwent neoadjuvant chemoradiation and left radical mastectomy with her clinical course complicated by disease recurrence with bone and bladder metastases 2.5 years after her initial diagnosis. We highlight the presentation and diagnosis of genitourinary involvement of metastatic IBC, which has not previously been described in the literature.

Musculoskeletal manifestations of syphilis in adults: secondary syphilis presenting with ankle inflammatory arthritis and bone involvement with calvarial and sternal lesions. What the rheumatologist needs to know.

Although the incidence of syphilis reached a historic low in 2000, the number of incident cases has since increased in men and women across the USA. In 2019, men who have sex with men (MSM) accounted for 57% of all primary and secondary (P&S) syphilis cases, and about half of MSM with P&S syphilis are living with human immunodeficiency virus (HIV) infection. Days after infection, Treponema pallidum disseminates and invades tissues distant from the site of inoculation. Once the spirochete disseminates, the host develops an inflammatory response; diagnosis requires a high level of suspicion since syphilis may affect the skin, musculoskeletal, cardiovascular, and central nervous systems. We report a 61-year-old man with virally suppressed HIV infection who presented with polyarthralgia, chest pain, and weight loss, diagnosed with secondary syphilis, manifesting with ankle inflammatory arthritis and bone involvement, of the calvarium and manubrium. Early and late syphilis in adults can manifest with articular and periarticular pathologies, including inflammatory arthritis, tenosynovitis, periostitis, and myositis. Higher clinical suspicion is needed for prompt diagnosis of syphilis in patients who are at risk and suspected of having an autoimmune disease. This report includes a review of the musculoskeletal manifestations of syphilis.

Surgical resection of a rare primary retroperitoneal mucinous borderline tumor of Müllerian Origin: A case report.

•Primary retroperitoneal mucinous tumors (PRMTs) are a rare group of cystic neoplasms consisting of three subtypes.•PRMTs are histologically similar to ovarian mucinous tumors but lack true ovarian tissue.•PRMTs should be considered in the differential diagnosis when encountering retroperitoneal cystic lesions.•During surgical resection tumor disruption should be avoided.•Surgical resection alone provides durable disease control for mucinous borderline tumors of low malignant potential.
