173 | A 49-year-old woman, with phototype I skin with no previous family or personal
history of melanoma, presented to our department for a total skin check-up. The
patient had numerous solar lentigines. Upon examination, a 9 × 4-mm brown irregular
macule on the right deltoid region was detected. The dermoscopy showed apparent
reticular pigmented pattern, along with some pigmented dots and a structureless
central area with white-grey structures. Left panel: Clinical presentation. Irregularly pigmented macule on the shoulder.
Multiple solar lentigos on the surrounding skin.
Right panels: Dermoscopic image of the lesion (Fotofinder® dermoscope, 10×).
The whole lesion couldn’t be included in a single image, hence it is depicted in
two panels.
An excisional biopsy was performed. Histopathological study showed atypical
melanocytes with pagetoid epidermal extension, confined to the epidermis, and
intense elastosis on the surrounding dermis. | /content/SkinCancerDataset_LC/SkinCancerDataset_LC/images/173.png |
174 | A 60-year-old woman, with phototype III skin and with no previous family or personal
history of melanoma, presented to our department for a total skin check-up.
One of his relatives, who was a physician, detected a 1-mm dark pigmented macule
on the right arm that had been previously unnoticed by the patient. The patient had
a moderate number of melanocytic nevi, predominantly macular. 10×-magnification
dermoscopic imaging showed homogeneous pigmentation. 40×-magnification dermoscopic
showed a central pigmented dark blotch, and surrounding pigmented dots
and apparent peripheral streaks.Clinical presentation. Minute darkly pigmented lesion on the lateral
aspect of the right arm. Other lighter and equally small pigmented lesions on the
surrounding skin. | /content/SkinCancerDataset_LC/SkinCancerDataset_LC/images/174.png |
175 | the attending dermatologist noted a tiny, approximately 3 × 2 mm,
dark brown macule lateral to his left orbit. On further questioning, the
patient revealed that the spot had been first noticed 4 years earlier, after a post-traumatic
contusion had healed. Dermoscopy showed multiple, white,
featureless areas throughout the lesion, with dots around the periphery and clods in
its central area. | /content/SkinCancerDataset_LC/SkinCancerDataset_LC/images/175.png |

177 | A 52-year-old woman, skin phototype III, presented with a 6-month history of a
rapidly-growing nodule on the left leg (Fig. 12.1). She denied any previous local
trauma or insect bite, as well as history of skin cancer.
Clinical inspection revealed a brown patch with irregular and poorly defined
borders, approximately 2.5 cm, with a 2 cm superimposed black and ulcerated nodule,
while dermoscopy showed a central structureless pink and ulcerated area, surrounded
by a yellowish area. There were also shiny white linear structures, areas of
superficial brown crusts, polymorphous vessels and a peripheral pigment network
(Fig. 12.2). The diagnosis of melanoma was considered. A fast-growing and ulcerated
nodule corresponding to vertical growth from a superficial spreading melanoma
(adjacent brown patch). The lesion was immediately excised.
Histologic examination revealed a nodular lesion occupying the entire dermis
and hypodermis, relatively well circumscribed, and composed of spindle cells, histiocytic
cells and multinucleated giant cells. There was xantomization and hemosiderin
deposition in the histiocyte’s cytoplasm (Fig. 12.3). A final diagnosis of a
hemosiderotic dermatofibroma was made. | /content/SkinCancerDataset_LC/SkinCancerDataset_LC/images/177.png |
178 | A 90-years-old patient underwent a surgery for a nodule on the vertex with the outcome
of non-ulcered nodular melanoma, which was dermis-infiltrating with 2.9 mm
Breslow. Associated to the nodular component there was an extended pigmented
lesion | /content/SkinCancerDataset_LC/SkinCancerDataset_LC/images/178.png |
179 | A 45-year-old female attended the Dermatology Clinic in 2014 for a pigmentary
tumor on the antero-lateral aspect of the right arm. She noticed the change of a preexisting
“brown spot” for the last two years (Clinical images: Fig. 18.1 and dermoscopy:
Fig. 18.2). During the last 12 months, the patient noticed the apparition of the
dark and blue pigmentations, of a small nodule and the increase in size of the tumor.
Her medical history revealed an invasive ductal carcinoma breast cancer type G3
that was diagnosed in 2008 | /content/SkinCancerDataset_LC/SkinCancerDataset_LC/images/179.png |
180 | An 58-year-old female patient came for a preventive exam in a screening campaign
for early diagnosis of melanoma. She pointed out the lesion on her arm, unable to
determine the duration of the lesion. Her personal and family history for cutaneous
malignances were negative. Previously, in her youth, she had unprotected UV exposure
during summer months. She was otherwise healthy, without chronic conditions,
and she was not taking any medication. Dermoscopy showed chaotic pigmented lesion, with mainly eccentric structureless
pattern eccentric black area, and central gray-brown hue. In the center of the
lesion, asymmetric dark brown unequally thick lines were noted. Segmental brown
radial lines were noticed at the periphery of the lesion as well as brown dots in
asymmetric fashion | /content/SkinCancerDataset_LC/SkinCancerDataset_LC/images/180.png |
181 | To confirm the diagnosis, he underwent an excisional biopsy, which was completed by sentinel lymph node biopsy. Histology confirmed the diagnosis of malignant melanoma, with Breslow thickness of 0.6 mm,Clark level II, without a vertical growth phase, mitosis, lymphatic or vascular invasion (Fig. 24.3).

with uneven borders, with

182 | A 54-year-old female presented with an irregular hyperpigmented lesion on her
right sole that quickly progressively developed for 1 year. Her lesion was itchy,
painless, and about 1.5 cm in diameter with a central ulceration that produced clear
discharge Before admitted, she went to private clinical and had
unknown diagnosis and treatment but the lesion didn’t improve. Dermoscopy
revealed a irregular
asymmetric lesion with
shiny white lines,
polymorphous vessel
hyperplasia, regression
structures and blue-white
veil sign | /content/SkinCancerDataset_LC/SkinCancerDataset_LC/images/182.png |
183 | A 54-year-old male farmer presented with a hyperpigmented macule on his right
heel that developed for 3 years ago. His lesion was non-itchy, painless and increased
in size rapidly and changed in color for 1 year. After that, he became hospitalized in
National Hospital of Dermatology and Vereneology. Physical examination revealed
not well-defined, irregular, 0.5-cm-diameter hyperpigmented plaque on the right
heel. No other lesions existed anywhere, and lymph nodes were not
enlarged. The rest of medical history was normal and none of his family members
had similar symptoms. Dermoscopy
revealed hyperpigmented
lesion in the form of stone
mosaic, irregular edges,
little scaly surface, regular
brown-to-black dots

184 | A 71-year-old man presented to the dermatology outpatient clinic because of pigmented
lesions on his inguinal area. In the inguinal area, 5 cm diameter, verrucous
pigmented lesion was observed dermoscopic examination of this lesion revealed
fissures and ridges cerebriform appearance, hairpin blood vessels, and moth-eaten
border. Verrucous carcinoma and melanoma were considered and biopsy
was taken. The lesion is
approximately 5 cm in
diameter, hyperpigmented
and contains nodular areas.
