    Abstract Introduction: Onychopapilloma most commonly presents as longitudinal erythronychia, but diagnosis may be challenging in some cases due to varied clinical presentations. Most patients with onychopapillomas do not report associated pain but instead more commonly report functional interference.
    Case report: We present a case of a 74-year-old female with a 5-year history of splitting and lifting of the right thumbnail, accompanied by nail sensitivity and intermittent painful throbbing. Clinical examination was significant for a less than 1 mm red line with distal onycholysis. Love's test and a cold test performed with ice pack were negative. X-ray of the right thumb was negative for erosion or exostosis. Nail biopsy was performed, and dermatopathology was consistent with onychopapilloma with a concomitant traumatic neuroma.
    Conclusion: We report a case of onychopapilloma with a concomitant traumatic neuroma. Subungual neuromas are extremely rare and have not previously been associated with onychopapilloma. Our case supports the expansion of the differential diagnosis for a painful nail and demonstrates the importance of diagnostic confirmation with biopsy and histopathology.

    Abstract Introduction: Localized longitudinal erythronychia is defined as a single nail with a longitudinal red band extending the length of a nail plate. It has a broad differential of benign and malignant etiologies, and is rarely due to benign vascular proliferations.
    Case presentation: We present a unique case of nail unit arteriovenous hemangioma presenting as longitudinal erythronychia of the left thumbnail in a 76-year-old male. The band was 6 mm and encompassed over 40% of the surface area of the nail plate. Dermoscopy showed red bands that were regular in terms of color, but not thickness or spacing. Due to concern for an amelanotic melanoma, a longitudinal excision was performed. Histopathology was consistent with a diagnosis of nail unit arteriovenous hemangioma.
    Conclusion: Arteriovenous hemangiomas were rarely present in the nail unit. They can be present as a blue or red nodule/macule, or as longitudinal erythronychia. Diagnosis often requires an excisional biopsy, with histopathology notable for a proliferation of multiple thick- and thin-walled vascular structures lined by a flattened endothelium. Our case emphasizes the need to consider vascular proliferations, such as arteriovenous hemangioma, in the differential diagnosis of longitudinal erythronychia.

    Abstract Lichen planus is a chronic inflammatory disorder that may affect the skin, nails, and/or oral mucosa. Bullous lichen planus is a rare variant of lichen planus, which is even less common in the nails. We present a case of nail bullous lichen planus, in a 48-year-old male presenting with a 10-month history of onychodystrophy of all ten fingernails. A longitudinal excision of the left thumbnail was performed, with histopathology consistent with lichen planus with focal transition to bullous lichen planus. He was treated with intralesional triamcinolone injections to the fingernails monthly, with improvements noted after three treatments. Our patient's nail bullous lichen planus manifested with longitudinal ridging, white-yellow discoloration, onycholysis, subungual hyperkeratosis, and v-shaped nicking. Histopathological findings included classical lichen planus changes, as well as formation of subepidermal bullae, colloid bodies, and extensive inflammatory infiltrate. Increased awareness and high index of suspicion for this condition are necessary, given the often late diagnosis reported in previously published cases.

    Abstract Introduction: Onycholemmal carcinoma (OC) is a rare subtype of squamous cell carcinoma (SCC) that originates from the epithelium of the nail bed. It is characterized by distinct histopathologic features including small clusters of atypical squamous epithelium devoid of a granular layer, with abrupt onycholemmal keratinization.
    Case presentation: We present a case of a 75-year-old male with right thumbnail onycholysis, yellow-green nail plate discoloration, as well as bleeding and purulence of the lateral nail fold. Histopathologic evaluation revealed high-grade squamous dysplasia, small clusters of severely atypical epithelial cells, and a pattern of abrupt keratinization consistent with the diagnosis of SCC carcinoma with onycholemmal features. GMS and PAS staining indicated concomitant onychomycosis. Pathologic analysis also disclosed residual SCC and concomitant amyloidosis, possibly light chain related and hence reflective of his underlying multi-organ lymphoplasmacytic lymphoma. The patient subsequently underwent Mohs micrographic surgery.
    Conclusion: Clinical presentation of nail unit SCC with onycholemmal features is highly variable, making differentiating between similarly presenting benign and malignant nail disorders particularly challenging. This case report demonstrates clinical and histopathological features of nail unit SCC with onycholemmal features to improve diagnosis and management.

    Abstract Clonally restricted, non-epidermotropic, low-grade, CD8-positive T-cell infiltrates of the skin was recognized as a unique form of indolent CD8-positive lymphoproliferative disease in 2007 when it was first called primary cutaneous indolent CD8-positive lymphoid proliferation. More recently, the designation of primary cutaneous acral CD8-positive T-cell lymphoproliferative disorder has been used. It is unique as a cutaneous lymphoproliferative disorder because of relative uniformity in its clinical presentation and histomorphology. It has been recognized as having an interesting predilection for the ear and acral sites, characteristically presenting as a solitary lesion. The basic morphology is one characterized by a non-epidermotropic, tumefactive infiltrate of well-differentiated, noncerebriform, atypical, small- to intermediate-sized lymphocytes that exhibit a specific phenotype characterized by CD8 and TIA positivity in concert with a distinct perinuclear Golgi staining pattern for CD68. The typical presentation is in the context of a solitary lesion, which can be treated surgically or with local irradiation. We describe in detail two very unusual cases that expand the clinical spectrum of this condition given the non-acral localization, the multiplicity of lesions to involve the trunk and extremities, and, in one case, the stable but recalcitrant course over 30 years. In addition, the second patient developed paraneoplastic dermatomyositis. We also retrospectively review our database for other cases that represent the entity of primary cutaneous acral CD8-positive T-cell lymphoproliferative disorder and review the literature focusing on non-acral cases. Nomenclature evolution from its first recognition in 2007 to the present is discussed.
