Background: Granulocytic sarcoma (GS) is a rare malignant tumor, and relapse is even rarer in the breast and dorsal spine following allogeneic hematopoietic stem cell transplantation. Currently, a standard treatment regimen is not available.
Case Summary: A rare case of GS of the right breast and dorsal spine after complete remission of acute myelogenous leukemia is reported here. A 55-year-old female patient presented with a palpable, growing, painless lump as well as worsening dorsal compressive myelopathy. She had a history of acute myelomonocytic leukemia (AML M4) and achieved complete remission after chemotherapy following allogeneic hematopoietic stem cell transplantation. Imaging examinations showed the breast lump and C7-T1 epidural masses suspected of malignancy. Histologic results were compatible with GS in both the right breast and dorsal spine, which were considered extramedullary relapse of the AML treated 4 years earlier.
Conclusion: A rare case of GS relapse following allogeneic hematopoietic stem cell transplantation and guidelines for treatment are discussed.

Background: While alterations in the vasculature supplying the breast have been extensively recorded, there is no information on the direct breast branches of the axillary artery (AA). An elucidation of the direct breast branches may prove beneficial during mammoplasty.
Objective: This study sought to investigate the anatomical characterization of breast vasculature utilizing three-dimensional (3D) technology to establish an anatomical foundation for therapeutic operations.

Arterial variations in the upper limb are of significant clinical importance, especially in procedures such as venepunctures, coronary artery bypass grafts, trauma reconstructive surgeries, brachial plexus nerve blocks, and breast reconstructions. This report presents previously undocumented arterial variations in the upper limbs in a 95-year-old female cadaveric donor. We observed bilateral superficial ulnar arteries originating at the cubital fossa, deviating from the previously reported origin at the proximal brachial artery.

Bone cancer pain (BCP) is one of the most severe complications faced by patients with cancer; however, current pharmacological options are limited. Curcumin has been demonstrated to possess anti-inflammatory and analgesic properties; however, our preliminary research found that the analgesic efficiency of curcumin is not high in BCP. Consequently, curcumin analogs have emerged as a significant focus of our research.

Granuloma annulare (GA) is a benign inflammatory skin condition that most commonly presents on the dorsal surfaces of the hands and feet. The etiology of GA is unknown; however, it has been associated with multiple triggers, including malignancy and targeted cancer therapy drugs. This case report describes a 66-year-old female with metastatic breast cancer on ribociclib who presented with painful, erythematous papules on the palmar surfaces of the hands.

- * This anatomical variation is significant due to its low occurrence and the need for surgeons to be aware of it during procedures involving the axillary region.
- * Lack of knowledge about the dorsalis major muscle arch can lead to complications during surgeries like axillary curage or breast reconstruction using a dorsalis major flap.
