Usher syndrome is a heterogeneous genetic disease that is the most common cause of hereditary blindness–deafness. This syndrome is the most prevalent syndrome associated with retinitis pigmentosa. A 25-year-old man referred to us with hearing loss and vision diminution since childhood which has gradually worsened. Visual acuity of both eyes was 20/100. Slit lamp examination of the left eye revealed endothelial stellate keratic precipitates, mild anterior chamber reaction, iris heterochromia, ectropion of uvea, and mild posterior subcapsular cataract. There were also no crypts and abnormal vessels in the left eye iris. His intraocular pressure was 14 mmHg in the right eye and 18 mmHg in the left one. Funduscopy demonstrated waxy pallor optic nerve, marked arterial narrowing, and retinal bone spicule pigment formation in both eyes. We report for the first time a very rare association between Usher syndrome, Fuchs heterochromic uveitis (FHU), and ectropion uvea. To our knowledge, no association has been reported between ectropion uvea, FHU, and Usher syndrome.

Extraintestinal manifestations (EIMs) are common in patients with Crohn's disease (CD). Various reactive cutaneous conditions, including erythema nodosum and pyoderma gangrenosum frequently occur as a part of EIMs. However, cutaneous metastasis of CD is rarely encountered in CD patients. Here, we report a 28-year-old female patient presenting with discharging deep fissures on genital and intergluteal regions. The result of a skin biopsy showed noncaseating granulomas. After rule out all the other differential diagnoses for granulomatous skin lesions, we believe this patient may be a case of CD, presenting with skin metastasis and GI tract involvement has not been occurred during 1-year follow-up. We suggest including cutaneous (metastatic) CD in the list of dermatologic differential diagnoses for cutaneous lesions of these sites. These lesions can occasionally precede gastrointestinal (GI) involvement by months and years, therefore, an appropriate follow-up needs to be done to detect GI lesions as soon as they appear.

Retropubic midurethral sling (MUS) is safe and effective surgery used for the treatment of stress urinary incontinence in women. Bladder neck perforation is a rare intraoperative complication. If this complication missed in intraoperative cystoscopy may have serious morbidity. A 52-year-old woman underwent a retropubic MUS. She presented with early and unusual symptoms such as suprapubic and labial cellulitis and urine leakage through the suprapubic incision 1 week after surgery which was due to a missed bladder neck perforation during surgery. In cystoscopy after MUS revealed mesh traversing the bladder neck and it was removed. The missed bladder perforation may have early and unusual symptoms and cystoscopy must be done more carefully and obsessively in patients with risk factors.

Primary breast lymphomas are uncommon tumors and account for <1% of all malignant neoplasms of the breast. They are almost always of non-Hodgkin type, with B-cell lymphomas being the most common subtype. Anaplastic large cell lymphoma (ALCL) is a rare T-cell lymphoma that can involve the breast. Most of the articles in the literature describe ALCL in association with breast implants. We present a 48-year-old woman with a left breast enlargement and no history of an implant. Microscopic sections showed a high-grade CD30-positive lymphoid neoplasm with frequent giant cells, which turned out to be a primary ALCL of the breast, giant cell-rich pattern. To our knowledge, no cases of primary ALCL, giant cell-rich variant, have been reported in the breast in the absence of an implant making our case unique.

The COVID-19 pandemic has raised concerns among physicians and patients with autoimmune disorders about how this viral infection affects the patients receiving immunosuppressive drugs. There are speculations about a higher incidence and severity of COVID-19 in patients receiving a variety of immunosuppressant drugs. However, we reported the rapid recovery from COVID-19 in a 67-year-old male with granulomatosis with polyangiitis who did not experience severe symptoms of the COVID-19 as expected, despite having a history of serious lung involvement due to the autoimmune disease. He received conventional medications to treat COVID-19, though he had been receiving rituximab and corticosteroids before the onset of COVID-19 symptoms. Prevention of the cytokine storm caused by SARS-CoV-2 infection owing to taking the immunosuppressive drugs (rituximab and corticosteroids) could be a reason for these unexpected observations. Therefore, this case showed that taking immunosuppressive drugs is unlikely to be directly related to the increased severity of COVID-19.
