A 69-year-old White man was referred to a dermatologist with an asymptomatic lesion on the nape of his neck. The lesion was a cherry-red plaque with no surface change. The patient had no history of trauma, skin cancer, or immunocompromisation. A biopsy revealed sun-damaged skin with thin-walled vessels and a mild lymphocytic infiltrate, leading to a diagnosis of acquired elastotic haemangioma (AEH). AEH is a rare condition that typically presents as a slow-growing plaque or patch on sun-exposed skin in older individuals. Treatment is not necessary, but excision may be performed for diagnostic purposes. [Extracted from the article]

The article describes the case of a patient in his 60s who has non-Hodgkin lymphoma (NHL) containing low-grade and two immunophenotypicaly and genetically distinct high-grade elements within the same lymph nodes. The patient complained of night sweats and a rapidly enlarging left supraclavicular lymph node. His tissue analysis showed a partly fragmented lymph node within which normal features had been effaced by a complex lymphoid neoplasm.
