BACKGROUNDsquamous cell carcinoma is the second most common type of skin malignancy and
may evolve to regional lymph node and distant metastases. OBJECTIVEThe objective of this study was to evaluate patients with head and neck
cutaneous squamous cell carcinoma to identify its clinical and
histopathological characteristics, as well as the frequency of local
recurrence and metastasis. METHODSA retrospective cohort of patients with head and neck cutaneous squamous cell
carcinoma. Inclusion criteria: histopathological confirmation, follow-up for
longer than one year after diagnosis. Exclusion criteria: immunosuppression;
lip and oral cavity squamous cell carcinoma; and non-surgical resection of
the lesion. We evaluated demographic, clinical and anatomopathologic
findings and explored their associations.RESULTSSixty-one patients with 79 tumors and followed by 4.8±3.0 years were
selected. The average age was 67.1 years, and 63% of tumors had up to two
centimeters. Seven tumors (8.9%) recurred and two of them had positive
margins. Recurrence was associated with higher Broders' grade (p<0.01).
Two patients (3.3%) had regional lymph node metastases. There were no
distant metastases. Seventy tumors were considered to be usual tumors
(89.7%), and 68 (87.2%) were classified as Broders' grade 1 and 2.
Additionally, 64.1% of tumors had a depth of invasion below four
millimeters. Thirteen tumors (16.7%) had positive histological margins. CONCLUSIONSMost patients had good prognosis in the first year of follow-up, confirming
that head and neck cutaneous squamous cell carcinoma has a better prognosis
than squamous cell carcinoma of other regions such as mucosa, oral cavity,
and internal organs.
