The present study describes the case of a male adult with an osteosarcoma in the proximal tibia, treated with limb salvage with endoprosthesis and chemotherapy. The patient developed an unusual metastatic pattern compromising the liver, bone, and inguinal lymph nodes, without local recurrence in the tibia or pulmonary metastases. Osteosarcoma (OS) is the second most frequent primary bone tumor after multiple myeloma in adults. Frequent sites of metastases in case of disease progression are the lungs and bone. Extrapulmonary metastases are rare. The development of new schemes of chemotherapy have improved life expectancy in osteosarcoma patients but have also altered the usual patterns of metastases, resulting in unusual metastatic locations.

Case report of a patient with a duodenal ulcer, initially treated with sclerosing agents, as is common practice for most bleeding ulcers. However, the evolution following this treatment is unusual. The patient developed secondary ischemic cholangitis, leading to extensive aerobilia and secondary portal pneumatosis, accompanied by inflammatory changes in the head of the pancreas.

Immunoglobulin G4-related disease (IgG4-RD) and systemic lupus erythematosus (SLE) are multisystemic autoimmune disorders that can present with renal manifestations. Overlapping cases of these diseases are extremely rare and present both diagnostic and therapeutic challenges. We report the case of a 70-year-old male with a history of autoimmune pancreatitis, who was admitted with fatigue, weight loss, and worsening kidney function.

Metastatic melanoma with unusual histopathology can be diagnostically challenging. One exceptionally rare cutaneous manifestation of metastases is blue-nevus-like metastatic melanoma (BNLMM). A 74-year-old male presented with a blue-gray lesion on his left helix in the same anatomical region of a previously resected lentigo maligna.

Purpose: Parathyroid carcinoma (PC) is an extremely rare disease, typically presenting with marked elevations of serum calcium concentrations and associated with significantly increased parathyroid hormone (PTH) levels. Although it progresses slowly, approximately25% of PC patients have lung metastases. In the present study, we aimed to evaluate the role of technetium-99m methoxy isobutyl isonitrile (Tc-99m-MIBI; sestamibi) SPECT/CT scintigraphy in the preoperative localization of parathyroid adenomas, incidental metastases findings of PC, and ectopic parathyroid tissue.

Prostate cancer frequently metastasizes to bones; however, the detection of metastases can be challenging in rare locations. We present the case of a 76-year-old man with metastatic castration-resistant prostate cancer with lymph nodal and skeletal metastases who underwent 177Lu-prostate-specific membrane antigen (PSMA) therapy. Initial 18F-PSMA PET/CT scan acquired until the midthigh failed to identify metastases in the foot, but posttherapy 177Lu-PSMA scan revealed the presence of metastases in the navicular and cuboid bones of the right foot, which is a very rare finding.
