The histopathological and dermoscopic correlation of primary cutaneous mucinous carcinoma

Intratumoral hemorrhage in some tumor lobules and proliferative blood vessels within the fibrous septa were also present [Figure 1]c and [Figure 1]d. Immunohistochemistry was done as demonstrated in in [Figure 1]e.{Figure 1} Case 2 A 64-year-old woman had one non-tender, slowly growing, erythematous nodule on her left lower eyelid for 2 years [Figure 2]a. Dermoscopy revealed translucent gray globules encircled with grayish-white areas in an arch-like pattern and linear irregular vessels located peripherally. [...]focal brownish area was also noted [Figure 2]b. Microscopic findings showed a nodule of cribriform glands with focal mucin production and blood vessels growing in fibrous septa [Figure 2]c. Perivascular hemosiderin deposition was present in the upper dermis [Figure 2]d. Immunohistochemistry done is shown in [Figure 2]e, [Figure 2]f, [Figure 2]g.{Figure 2} Case 3 A 49-year-old man presented with a slowly growing, nontender, brownish translucent nodule on his left temple for 2 to 3 years [Figure 3]a. Dermoscopic examination showed multiple translucent gray area, clusters of whitish cloud-like structure, purplish globules, as well as scattered brownish areas [Figure 3]b. Histopathology showed a dermal nodule composed of cribriform epithelial cells in mucin lakes. Some of fibrous septa were ruptured and the debris floated in mucin pools [Figure 3]c.{Figure 3} Case 4 A 48-year-old man had one slowly growing, nontender, translucent erythematous nodule on his left cheek for 5 years [Figure 4]a. Dermoscopy showed multiple translucent gray area and pinkish globules separated by whitish halo-like structures, focal purplish globules, as well as short, linear, irregular and dotted vessels [Figure 4]b. Histopathology revealed a dermal nodule composed of tumor nests with glandular lumina in pools of mucin separated by fibrous strands.
