Cylindroma is a rare benign neoplasm of probable origin in the eccrine sweat glands and is characterized by papular and nodular, painless, slow-growing lesions, generally located on the head, neck and scalp. When multiple, they can be part of hereditary syndromes. The authors report the case of a patient with a solitary nodulation on the scalp, presenting pathological examination compatible with cylindroma. The lesion was excised, with satisfactory results and no recurrence.

Although primary cutaneous amyloidosis (PCA) is prevalent worldwide, it is underdiagnosed. Among the subtypes, nodular amyloidosis (NA) is the rarest. There is no consensus in the literature; treatment is challenging, and no therapy has been proven effective. The authors report the case of a patient with a nodule in the nose, whose anatomopathological examination was compatible with amyloidosis, with no evidence of systemic disease. It was then classified as nodular PCA. The lesion was excised satisfactorily. It was concluded that surgical removal is an effective therapy for the treatment of NA.

INTRODUCTION: Cutaneous malignant tumors are preventable and have a high cure rate when diagnosed early, resulting in reduced morbidity and mortality. Early-stage cancer detection allows for timely treatment, leading to a better prognosis.
OBJECTIVE: To evaluate the effectiveness of the "Skin Cancer Awareness Month" campaign in identifying potential cases of skin cancer and its resolution rate based on the time required for lesion treatment.
METHOD: A retrospective analytical cross-sectional study with descriptive-quantitative characteristics.
RESULTS: In 2022, the time between biopsy and curative surgery ranged from 94 to 218 days, with a median of 153 days. In 2023, the time between biopsy and curative surgery ranged from 12 to 249 days, with a median of 129 days. A statistically significant difference (p=0.04) was observed between the years 2022 and 2023 in the median time from biopsy to surgery.
CONCLUSION: Improved efficiency in performing biopsies and surgeries, as well as enhanced patient adherence to treatment, was necessary.
