BackgroundCutaneous squamous cell carcinoma (SCC), which occurs in keratinocytes of the epidermis and is the second most common skin cancer, has a more invasive growth pattern and higher potential to metastasize than basal cell carcinoma. Total excision of the primary tumor is the treatment of choice. For clear excision of the tumor, invasion depth is one of the most important factors. This study was conducted to clarify the relationship between the size and the invasion depth of cutaneous SCC.MethodsTwenty-six cases were collected for this prospective study. Frozen biopsies were examined after complete resection of the tumor, followed by histological confirmation by pathological examination. The major and minor axis lengths of the tumor, the invasion depth, and the level of invasion were measured. Recurrence or metastasis was recorded through regular follow-up.ResultsThe Pearson correlation coefficient was used for statistical analysis. Significant results were observed for the relationship between the major and minor axis lengths and the invasion depth of the tumor (0.747, 0.773). No cases of recurrence or metastasis were observed.ConclusionsIn head and neck cutaneous SCC, the invasion depth of the tumor is closely related to the major and minor axis lengths of the tumor. Therefore, the invasion depth of the tumor can be estimated by measuring the size of the tumor, and a standard vertical safety margin for head and neck cutaneous SCC can be established, which could be helpful in the development of a preoperative reconstruction plan.
Rationale:Apocrine carcinoma is a rare malignant sweat gland tumor that has been reported in approximately 200 cases. This tumor usually occurs in the axilla, but in rare cases, it can also develop in the scalp. In the present work, we report 2 cases of cutaneous apocrine carcinoma of the scalp.Patient concerns:Two men visited our outpatient clinic with recurrence of tumor after undergoing surgery for scalp tumor at another hospital.Diagnoses:Brain magnetic resonance imaging of a 56-year old man showed the presence of a 5.0 × 4.5 × 4.4 cm scalp mass in the right parietal region, invading the skull and dura mater and a 2.2 × 2.0 × 0.7 cm bony mass without any skin lesions right next to the scalp mass. Neck magnetic resonance imaging of a 76-year-old man revealed the presence of a well-defined oval mass in the subcutaneous layer of the left occipital scalp and 2 enlarged lymph nodes in the left neck. Definite diagnoses were made postoperatively. The patients were diagnosed with cutaneous apocrine carcinoma. The diagnosis was confirmed through histopathological and immunohistochemical staining tests.Interventions:The tumors were removed with a wide safety margin and reconstructive surgery was performed.Outcomes:Additional radiotherapy or chemotherapy was performed. Follow-up more than 6 months revealed no recurrence or metastasis.Lessons:If accurate diagnosis and treatment had taken place at the initial stages of the primary cutaneous apocrine carcinoma, it would have been possible to prevent recurrence and intracranial invasion. As recurrent primary cutaneous apocrine carcinoma can become aggressive and difficult to treat, even a small mass on the scalp must be evaluated carefully and treated properly.
For orbital floor blowout fractures, open reduction and internal fixation using absorbable mesh plates and screws was a feasible alternative to orbital floor reconstruction.
Seromas commonly occur or recur after reconstructive surgery in patients with pressure ulcers, often leading to infection, increasing the risk of wound dehiscence and flap necrosis, and therefore requiring an additional surgical procedure. Various strategies have been employed to treat seroma, such as retaining as much of the fascia as possible, using progressive tension sutures, inserting suction drains, utilizing sclerotherapy, or applying compression via dressings or specialized garments. However, despite these efforts, seroma prevention remains difficult. In the current report, we describe three cases in which we administered Viscum album extract to prevent and treat seromas that developed following pressure ulcer reconstruction. V. album extract sclerotherapy was performed in a patient with a recurrent seroma, a patient with a persistent seroma, and a patient wishing to undergo sclerotherapy immediately postoperatively as a prophylactic treatment. The seromas resolved shortly after initiating treatment, and recurrence was not observed at any of the subsequent outpatient follow-up visits. These cases suggest that sclerotherapy with V. album extract following pressure ulcer reconstruction can suppress development of seromas and lower the risk of recurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
