The blastoid variant represents a highly aggressive form, with a high mitotic index and unfavorable prognosis. Cutaneous involvement by mantle cell lymphoma is rare and may present with atypical clinical features, often leading to delayed diagnosis due to morphological overlap with other high-grade lymphomas and unusual extranodal presentations. We describe a 73-year-old male who presented with a solitary fluctuant swelling over the left cervical region clinically suspected to represent an abscess, without systemic symptoms or lymphadenopathy. Contrast-enhanced imaging revealed a localized lesion without additional lymphadenopathy. Histopathological examination of a core biopsy demonstrated medium to large atypical lymphoid cells. Immunohistochemistry showed strong expression of CD20, CD5, cyclin D1, SOX11, and a high Ki-67 proliferation index (~90%–95%), supporting a diagnosis of blastoid variant MCL. These cells were immunonegative for CD3, CD10, BCL6, and CD30, excluding other high-grade lymphomas. This case highlights an unusual presentation of blastoid mantle cell lymphoma, manifesting as an abscess-like cutaneous lesion of the neck and underscores the importance of histopathologic and immunophenotypic evaluation in atypical cutaneous swellings.

Since normal scalp is not routinely biopsied, a control group was not included in that study. To reinforce our findings, we selected 18 scalp biopsies from patients who complained of hair loss but showed no inflammatory infiltrate or fibrosis in the dermis or follicular regions upon histological examination. These were considered representative of normal scalp tissue and served as our control group. All specimens were obtained with 4 mm punch biopsy. Horizontal sections parallel to the epidermis were performed at 1 mm intervals down to the hypodermis in 31 cases of Frontal fibrosing alopecia (FFA), 29 cases of Fibrosing alopecia in a pattern distribution (FAPD), and 11 cases of Lichen planopilaris (LPP), which were selected based on clinicopathologic and trichoscopic correlation, as well as in 15 cases of normal scalp. Three normal scalp biopsies were sectioned vertically but were included, given that normal scalp biopsies are rarely obtained. All samples were processed and evaluated using deeper serial sections, allowing detailed visualization of the structures.&lt;/p&gt;&lt;p&gt;To better illustrate our findings, we will briefly review normal scalp histology in which the hair follicle is divided into an upper segment (ostium, infundibulum—Figure 1a, and isthmus—Figure 1b) and a lower segment (suprabulbar and bulbar), separated by the bulge zone, where the arrector pili muscle (APM) inserts (Figure 2a). Horizontal sections may show the epidermis and follicle insertion at the ostium and infundibular levels (Figure 1a). The isthmus ranges from the sebaceous duct to the APM attachment at the bulge [&lt;span&gt;2&lt;/span&gt;] (Figures 1b and 2a).
