The clinicians should be aware that clinically, verruciform
xanthoma may mimic malignancy.
xanthoma of the esophagus," Human Pathology, vol.
Histologically, a papillomatous pattern with acanthosis is noted in all the cases of verruciform
lesions and thus they may mimic each other both clinically and on microscopy (Table 1) [2, 10-12].
plaques appeared on the second and fifth fingertips of the right hand and left hand, respectively, which progressed until revealing necrosis areas (Photographs 1, 2, and 3).
On histopathology, warty HSIL and SCC mimic condyloma acuminatum by their verruciform
architecture, conspicuous fibrovascular cores, and koilocytosis (Figure 4, A).
Histologically, besides the hallmark of a superficial plate-like epithelial proliferation, some variations are occasionally reported: the presence of randomly scattered keratin-filled cysts, squamous eddies, minimal peripheral palisading, marked verruciform
architecture, and a reticulated pattern with elongated strands of keratinocytes.
These are either benign or reactive, for example, papilloma, verruca vulgaris, fibroepithelial polyp and verruciform
xanthoma, which usually present with little diagnostic difficulty.
In industrialized nations, penile carcinoma is rare, accounting for less than 1% of all tumours in men.[sup.1] Ninety-five percent of penile carcinomas are classified as primary epithelial squamous cell carcinoma (SCC).[sup.2] Variants include basaloid, condylomatous, verrucous, papillary not otherwise specified (NOS), sarcomatoid, adenosquamous and mixed carcinomas.[sup.3] The verruciform
carcinomas of the penis are a heterogeneous group of exophytic, generally low-grade SCC.
dVIN should be differentiated from other verruciform
lesions, including uVIN with superimposed LSC, verruciform
LSC, vulvar acanthosis with altered differentiation (VAAD), and verrucous carcinoma.
A 68-year-old woman presented with a scaly verruciform
plaque on the chin that had been present for 10 to 15 years.
The low-risk group includes verruciform
tumors such as verrucous, papillary, and warty/condylomatous carcinomas.
or papillomatous PEH is difficult to separate diagnostically from verrucous squamous carcinoma.
