Background: Rectal mucinous adenocarcinoma (MAC) is a rare pathological type of rectal cancer with unique pathological features and a poor prognosis. It is difficult to diagnose and treat early because of the lack of specific manifestations in some aspects of the disease. The common metastatic organs of rectal cancer are the liver and lung; however, rectal carcinoma with metastasis to subcutaneous soft tissue is a rare finding.
Case Summary: In this report, the clinical data, diagnosis and treatment process, and postoperative pathological features of a patient with left waist subcutaneous soft tissue masses were retrospectively analyzed. The patient underwent surgical treatment after admission and recovered well after surgery. The final pathological diagnosis was rectal MAC with left waist subcutaneous soft tissue metastasis.
Conclusion: Subcutaneous soft tissue metastasis of rectal MAC is rare, and it can suggest that the tumor is disseminated, and it can appear even earlier than the primary malignant tumor, which is occult and leads to a missed diagnosis and misdiagnosis clinically. When a subcutaneous soft tissue mass of unknown origin appears in a patient with rectal cancer, a malignant tumor should be considered.

A boy in his middle childhood presented with a gradually enlarging, mildly tender swelling in the left frontal region, noticed after minor trauma. Skull radiograph and non-enhanced CT revealed a diffuse sclerotic lesion involving the left frontal bone and overlying subcutaneous soft tissue, suggestive of an intraosseous haemangioma. Contrast-enhanced MRI showed an expansile, hypointense lesion in the frontal bone on the left side with enhancing extraosseous components and a small extra-axial cyst.

Methods: Client-owned dogs (n = 83) were enrolled in a randomized, blinded, placebo-controlled clinical study for dogs undergoing a variety of soft tissue surgical procedures between March 31, 2021, and August 18, 2022. After incision closure, an injection of a placebo (0.

Owing to the high invasion depth and easy formation of biofilms, the treatment of subcutaneous fungal infection is intractable and challenging. Herein, we report an injectable and biodegradable hydrogel with bactericidal, quorum sensing inhibition and antioxidant activities for the in situ treatment of subcutaneous fungal infection. The hydrogel (BEPE) was constructed by irradiating mixed bovine serum albumin (BSA), ε-polylysine and epigallocatechin gallate (EGCG)-loaded mesoporous polydopamine (PDA) under near-infrared (NIR) light.

Necrotizing fasciitis (NF) is a rare but life-threatening soft tissue infection, often accompanied by severe systemic toxicity. Early detection and prompt treatment are critical for survival. We report a case of NF in a 53-year-old diabetic woman following a subcutaneous insulin injection in the thigh.

Producing oral soft tissues using tissue engineering could compensate for the disadvantages of autologous grafts (limited availability and increased patient morbidity) and currently available substitutes (shrinkage). However, there is a lack of in vitro-engineered oral tissues due to the difficulty of obtaining stable pre-vessels that connect to the host and enable graft success. The main objective was to assess the connection of pre-vascularised 3D-bioprinted gingival substitutes to the host vasculature when subcutaneously implanted in immunodeficient mice.
