Key Clinical Message: Mycosis fungoides is a diagnostic challenge. Herein, we report a case with marked lichenoid features in pathology assessments. After several biopsies and clinicopathologic correlation, the diagnosis of lichenoid mycosis fungoides was made. Mycosis fungoides (MF) is a great imitator and mimicks other dermatoses clinically and histopathologically. We report a 61‐year‐old patient with 5‐year history of generalized violaceous patches and plaques. His biopsy revealed a marked lichenoid band‐like infiltrate of inflammatory cells along the basal layer with basal layer vacuolar changes; the diagnosis of lichen planus was first made histopathologically. Several biopsy specimens, clinicopathologic correlation, and immunohistochemistry findings confirmed the diagnosis of lichenoid MF. Awareness of peculiar histopathologic findings of MF is essential to avoid a potential misdiagnosis. When in doubt, multiple biopsies with other diagnostic methods should be employed.

Key Clinical Message: In a resource‐limited setting such as Sudan, where diagnostic and surveillance capacities are limited and several dermal diseases with similar clinical presentation are endemic, further precautious must taking into account. Cutaneous tuberculosis (CTB) is a rare infection caused by Mycobacterium tuberculosis. Atypical clinical presentations of CTB may resemble other skin neglected diseases. For definitive diagnosis, we require a holistic diagnostic approach including clinical examination and deployment of laboratory investigations including microbial culture, histopathological, and molecular examinations of the proper samples per test. In this communication, we report a case of CTB that was initially misidentified clinically as mycetoma. [ABSTRACT FROM AUTHOR]

Abstract It was critical for the clinician to be aware of the neuroimaging and early‐onset symptoms of this fatal neurodegenerative disease, and avoid initiating inappropriate therapy. Neuroimaging plays a key role in differentiating it from other mimics.
