Tumor of the follicular infundibulum is a rare benign cutaneous adnexal neoplasm with
variable clinical presentation. In most cases the diagnosis is made with the help of
histopathology, due to lack of a characteristic clinical presentation. The most
common form is a solitary lesion, but it can be multiple or eruptive, then called
infundibulomatose. This case report illustrates a patient with multiple lesions of
tumor of the follicular infundibulum with bizarre aspect and atypical location.
Sarcoidosis is a multisystem granulomatous disease of unknown cause. The
osteoarticular involvement in sarcoidosis is rare and is often associated with
cutaneous and long-standing chronic multisystem disease. More common in black
women, osseous sarcoidosis is difficult to diagnose, with an incidence of 3 to
13%. The most characteristic radiological clinical picture evidences rounded,
well-defined cysts, with no periosteal reaction and without peripheral
sclerosis. The small bones of hands and feet are the most frequently involved
sites. This report aims to demonstrate a rare case of osteoarticular sarcoidosis
with characteristic clinical presentation, and highlight the importance of
detecting osteoarticular involvement in this pathology.
Cutaneous metastasis is a rare manifestation of visceral malignancies that indicates
primarily advanced disease. Due to its low incidence and similarity to other
cutaneous lesions, it is not uncommon to have a delayed diagnosis and a shortened
prognosis. We describe the case of a patient who presented with a cutaneous nodule in
the sternal region as a first sign of malignancy.
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.
