Coexistence of esophageal blue nevus, hair follicles and basaloid squamous carcinoma: A case report

Figure 1 Arrangement of basaloid cells in the form of anastomosing trabeculae and microcystic structures. The microcystic spaces contained basophilic mucoid matrix, mimicking an adenoid cystic carcinoma. The cells at the edges of basaloid islands tended to show peripheral nuclear palisading. Comedo necrosis was observed in the center of basaloid lobules (HE, × 40).
