چکیده
Case 1: A man in his fifties with a history of Hodgkin lymphoma treated 20 years prior with the Stanford V protocol and mantle field radiation (total dose: 36 Gray) presented for skin examination. A 3 mm pedunculated pink papule was found on the right chest within the prior radiation field (Figure 1A). The lesion was asymptomatic and of unknown duration. There was no history of change, bleeding, or itching. Polarized dermoscopy of the papule revealed irregular linear and looped branching vessels that terminated in a semicircular or circular fashion, also termed “cherry-blossom” vessels (Figure 2A). Histopathologic examination revealed a pedunculated well-circumscribed nodular epithelial tumor composed of uniform cuboidal cells with round basophilic monomorphic nuclei. Multiple broad cords of the anatomizing tumor epithelium connected to the overlying epidermis, surrounding characteristic sclerotic well-vascularized stroma (Figure 3A). Case 2: A woman in her fifties with a history of basal cell carcinoma and B-cell acute lymphoblastic leukemia status post two allogenic hematopoietic stem cell transplants (total body irradiation induction dose of: 13.75 Gy) presented for skin examination. A new, asymptomatic 2 mm pedunculated pink papule was found on the presternal chest (Figure 1B). Polarized dermoscopy of the lesion revealed semicircular/ circular branching vessels originating from a common stem vessel (Figure 2B). Histopathological examination revealed a polypoid epithelial tumor comprised of broad downgrowths of cuboidal epithelium clearly demarcated from overlying epidermis amidst a background of hyalized/sclerotic highly vascular stroma. Small ducts with a pink cuticle were noted within epithelial bands (Figure 3B). What is the diagnosis? Isolated pink papule on the chest

The most common and well known is nevus Sutton or halo nevus first described in medical journals in 1916, where a hypopigmented area develops around a pre-existing melanocytic nevus. Halo nevi undergo specific sequelae: In Stage I the nevus remains brown, in stage II its pigment can disappear leading to a pink-colored papule. In stage III the central papule disappears, leading to a circular are...

A 65-year-old man presented with an asymptomatic lesion on the left parietal scalp of 6 months’ duration. Three years prior, a cylindroma on the same area was excised by a general surgeon. Physical examination revealed a solitary 6 mm salmon-pink, firm, dome-shaped papule on the left parietal scalp (Figure 1). Dermatoscopic evaluation showed arborizing telangiectasia and several scattered white...
