Introduction: Primary breast lymphoma (PBL) is rare, and most cases occur in female patients, with few reported cases in male patients. The clinical presentation is similar to that of breast cancer, but the condition needs to be well understood, as treatment options and clinical course vary. Hence, we provide a relatively rare case of primary breast diffuse large B cell lymphoma (PB-DLBCL) in a male, including its complete clinicopathological features, radiological findings, genomic mutational profiles, and clinical course.

- Early diagnosis of SAPHO syndrome can be challenging as it often mimics other spine-related conditions; there’s no universal diagnosis method and treatments are diverse due to its rarity.
- A 62-year-old woman experienced persistent low back pain and was initially treated for adjacent segment degeneration after lumbar surgery; however, her symptoms persisted until signs of hyperkeratosis and osteitis led to the correct diagnosis of SAPHO syndrome.
- After being treated with medications including adalimumab, the patient’s symptoms improved significantly, showing complete recovery after 12 months, with no recurrence during follow-up.
Purpose: To construct an optimal radiomics model for preoperative prediction micropapillary pattern (MPP) in adenocarcinoma (ADC) of size ≤ 2 cm, nodule type was used for stratification to construct two radiomics models based on high-resolution computed tomography (HRCT) images.
Materials And Methods: We retrospectively analyzed patients with pathologically confirmed ADC of size ≤ 2 cm who presented to three hospitals. Patients presenting to the hospital with the greater number of patients were included in the training set (n = 2386) and those presenting to the other two hospitals were included in the external validation set (n = 119).
