A Rare Case of Dual Metachronous Primary Malignancies, Chronic Myeloid Leukemia, and Tongue Carcinoma in a Patient With Long-Standing Systemic Lupus Erythematosus: A Case Report and Review of Literature.

Patients with long-standing autoimmune diseases like systemic lupus erythematosus (SLE) are at a higher risk of developing hematological malignancies. However, chronic myeloid leukemia (CML) has rarely been reported in patients with SLE. Advancements in medical diagnostics and treatment have led to the life expectancy of SLE and CML patients moving closer to that of the general population, and it is not uncommon to encounter more than one malignancy in a cancer survivor. Although squamous cell carcinoma (SCC) of the skin has been reported in CML patients, mucosal SCC of the head and neck has rarely only been reported in CML survivors. The objective of this case report is to share our experience in treating a patient with dual metachronous primary malignancies, CML, and tongue carcinoma, along with long-standing SLE, managed by a multidisciplinary team.

Primary unilateral conjunctival small lymphocytic lymphoma in a child: Case report and literature review.

Ocular adnexal lymphomas (OALs) are extranodal lymphomas primarily involving the ocular adnexa, which includes the conjunctiva. OALs are considered primary if the involvement of lymphoma is confined to the ocular adnexa alone and secondary if there is lymphoma of the identical type present at another site. Conjunctival lymphomas are uncommon in children, with very few reported cases in published literature, none of which were small lymphocytic lymphomas (SLLs). We report a case of SLL confined to the conjunctiva, in a 15-year-old child, with full pediatric oncology examination, including full body positron emission tomography (PET) scan, revealing no other site involvement. To our knowledge, this is the first case to be reported of a child with primary unilateral conjunctival SLL.

Fonsecaea associated cerebral phaeohyphomycosis in a post-COVID-19 patient: A first case report.

Phaeohyphomycosis, previously known as chromoblastomycosis, is a chronic mycosis, usually affecting the skin. It is caused by dematiaceous fungi, which are a group of fungi that produce melanin in their cell walls. Cerebral phaeohyphomycosis occurs as a part of invasive presentation of the fungi, which usually affects immunocompromised patients, but may affect immunocompetent individuals as well. Cerebral infection in phaeohyphomycosis is associated with a poor prognosis regardless of the immune status of the patient. COVID-19 SARS-CoV-2 infection and/or medications used for its treatment may compromise the immune system, including in the post-COVID-19 period, resulting in invasive fungal infections, which have frequently been reported recently during the COVID-19 pandemic. We report a case of Fonsecaea associated cerebral phaeohyphomycosis in a recently diagnosed diabetic Omani lady, who presented to our hospital 6 weeks after recovery and discharge from hospitalization for moderate COVID-19 pneumonia.

Small and Thin Oral Squamous Cell Carcinomas may Exhibit Adverse Pathologic Prognostic Features.

We set out to record the frequency of recognised adverse pathologic features in early oral squamous cell carcinoma (OSCC) and correlate with neck disease, in particular in small and thin carcinomas, a group that might be assumed to behave less aggressively. We also examined the possibility of a biopsy site interfering with assessment of WPOI5 in small tumors. We reviewed all OSCCs ≤ 20 mm size and ≤ 10 mm depth reported at our institution over a 5-year period. Tumor maximum dimension, depth, perineural invasion (PNI), lymphovascular invasion (LVI), worst pattern of invasion (WPOI), and nodal status were recorded. Out of 95 cases, there were 44 (46.3%) small and 78 (82.1%) thin OSCCs. Depth and WPOI were significant factors in predicting nodal disease. There were 41 (43.2%) OSCC that were small and thin, of which 9.8% had PNI, none had LVI, and 61% had WPOI 4 or 5. Their rate of PNI and of nodal disease was similar to the other early OSCC. Assessment of WPOI5 at a biopsy site was only a problem in 2/38 cases. In early OSCC, depth and WPOI are important factors in predicting nodal disease. The very earliest OSCC (small and thin) have a similar rate of PNI and of nodal disease to other early OSCC, suggesting that while there may be a tendency to de-escalate treatment, these small tumours should be managed in the same way as for all early OSCC. In addition, the presence of scarring due to a biopsy in very small carcinomas rarely affects assessment of WPOI5.

An unusual relapse in acute myeloid leukaemia.

A 40-year-old nulliparous woman, with a history of acute myeloid leukaemia (AML), presented at a gynaecological clinic with an incidental finding of a 5 cm pelvic mass on ultrasound during workup for subfertility. Biopsies confirmed a myeloid sarcoma. The patient underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy, followed by chemotherapy and radiotherapy. She recovered well from her surgery, 21 months postsurgery with no evidence of recurrence.
