“…In previous reports, 1–4 the clinical characteristics of polypoid BCC often include accompanying inflammation, ulcers, scales or rough surfaces. However, our case was an atypical polypoid BCC because the surface was very smooth and not inflammatory 5 . Moreover, the favorable lesions of polypoid BCC are scalp, genital area, back‐buttock, and so on 6 .…”

Dear Editor, Basal cell carcinoma (BCC) as a polypoid tumor is very rare, especially on the face. It is unusual but possible for BCC to present a pedunculated feature. We describe a case of polypoid BCC on the face.A 70-year-old man presented a 10-year-old mass under the left eyelid region. The mass was a smooth, elliptical, and blackish-brown pedunculated polypoid tumor 7-mm across at maximum. We diagnosed it pathologically as the solid type of BCC. It is unusual but possible for BCC to present a pedunculated feature. It is significant to think of BCC as a differential diagnosis when we see a blackish polypoid tumor.The patient was a 70-year-old male who visited our clinic for tinea pedis. We recognized a pedunculated polypoid growth on his left palpebra although that was not his main complaint. He described how he had that tumor for more than 10 years and it had grown bigger. A soft mass, 7-mm across at maximum, was pedunculated on the lower part of the left eye absconsio. The whole mass was a blackish brown, while the stalk had a normal skin color. The surface was flat, elliptic and smooth (Fig. 1). Clinically, the differential diagnoses were of neurofibroma or a pigmented nevus.We performed a local excision with a small margin. The skin specimen revealed tumor of nests, composed of basaloid cells, extending from the upper dermis to the lower layer ( Fig. 2a). Each nest had rich melanin. Peripheral palisading and clefts between tumor nests and stroma were observed (Fig. 2b). The tumor aggregations were limited to the polypoid area and surgical margins were negative. Neither keratinization, cystic structure nor follicular differentiation were observed.We diagnosed this tumor as a solid type BCC.In the 12 months since the operation, there has been no recurrence.As the majority of skin carcinomas, BCC occupies approximately a half of all skin carcinoma cases. The occurrence of BCC in the form of a polypoid tumor, however, is an unusual clinical presentation, 1 except for the premalignant fibroepithelial tumor (Pinkus tumor), a variation of BCC. The tumor reported here is a very rare distinctive clinicopathological variant.In our case, histologically, tumor aggregations were restricted to a pedunculated zone. McElory et al. Figure 1. Clinical feature was a pedunculated blackish polypoid tumor.

“…e author characterized BCC as follows: polypoid appearance, female predominance, and tumor restriction within the polypoid area. Our search identified 22 previously reported cases of polypoid BCC described in the English literature (Table 1) [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. In our search, Gaughan [3] reported a giant pedunculated BCC on the forearm which arose from burn scar.…”

Polypoid Basal Cell Carcinoma on the Nose Tip

Basal cell carcinoma (BCC) is usually seen on the face as a pigmented nodule. We herein report a patient who presented with a polypoid BCC on the nose tip. Clinically, we suspected adnexal tumor; however, the findings of dermoscopy were consistent with that of BCC. Although the tumor was excised at the stalk, it was completely resected. Since the clinical manifestation was characteristic, we reviewed previously reported polypoid BCCs and found that this tumor can occur at any site, including the trunk and inguinal region, which are not preferential sites for ordinary BCC. There have been no reports of polypoid BCC on the nasal tip. The initial diagnoses varied, including adnexal tumors, and dermoscopic examinations proved useful for suspecting polypoid BCC. Histopathologically, the tumor cells in the resected specimens were within the polypoid area. Although BCC is a common tumor, polypoid BCC has distinct clinical features, and we should keep this rare subtype in mind.
