1A 58-year-old male presents with an asymptomatic, irregularly shaped, dark brown-to-black macule with variegated pigmentation on the hard palate. Incisional biopsy reveals malignant melanocytes invading the lamina propria. Which immunohistochemical marker profile is most characteristic and useful for confirming primary oral mucosal melanoma?
A.S100, Melan-A, HMB-45 and SOX10 positive; cytokeratin negative
B.Cytokeratin AE1/AE3, p63, and p40 positive; S100 negative
C.CD31, CD34, and ERG positive; HMB-45 negative
D.Desmin, MyoD1, and Myogenin positive; SOX10 negative
Explanation: Primary oral mucosal melanoma characteristically demonstrates strong positivity for melanocytic markers including S100, Melan-A (MART-1), HMB-45, and SOX10, while epithelial markers such as cytokeratins are typically negative. SOX10 and S100 are sensitive markers for neural crest-derived melanocytes, whereas HMB-45 and Melan-A provide higher specificity for melanocytic differentiation.
2A 34-year-old female presents with a rapidly growing, painless, dark brown flat-to-slightly elevated lesion on the right buccal mucosa that developed over the past 3 weeks. Biopsy reveals hyperplastic stratified squamous epithelium containing numerous dendritic melanocytes scattered throughout the spinous layer. Which of the following is the most likely diagnosis?
A.Superficial spreading melanoma
B.Oral melanoacanthoma
C.Intraoral blue nevus
D.Physiological (racial) pigmentation
Explanation: Oral melanoacanthoma is a benign, reactive mucosal lesion characterized clinically by rapid enlargement (often alarming clinicians) and microscopically by dendritic melanocytes interspersed throughout a hyperplastic spinous layer. It exhibits a predilection for black females and the buccal mucosa, and it often undergoes spontaneous resolution following incisional biopsy.
3Which of the following histopathological features distinguishes an oral melanotic macule from an intraoral junctional nevus?
A.Pleomorphic melanocytes exhibiting upward pagetoid spread into superficial epithelial layers
B.Aggregates of nevus cells clustered along the dermo-epidermal junction
C.More basal melanin without extra melanocytes or nest formation
D.Extensive subepithelial melanin incontinence with dense band-like lymphocytic infiltrates
Explanation: Oral melanotic macules are characterized by increased melanin synthesis and accumulation in basal keratinocytes and the lamina propria (melanin incontinence) without an increase in the number of melanocytes and without the formation of melanocytic theques or nests. Junctional nevi, in contrast, display distinct nests of melanocytes (theques) situated at the tips of rete ridges along the basement membrane.
4A 16-year-old male is evaluated for multiple 1- to 4-mm dark brown macules distributed across his vermilion border, perioral skin, and labial mucosa. His medical history is notable for recurrent episodes of colicky abdominal pain due to small bowel intussusception. Which gene mutation is responsible for this condition?
A.NF1 tumor suppressor gene
B.APC tumor suppressor gene
C.PTEN tumor suppressor gene
D.STK11 (LKB1)
Explanation: The clinical presentation of perioral and mucosal melanotic macules combined with small intestinal hamartomatous polyps leading to intussusception is classic for Peutz-Jeghers syndrome. This autosomal dominant disorder is caused by germline inactivating mutations in the STK11 (serine/threonine kinase 11, also known as LKB1) tumor suppressor gene on chromosome 19p13.3.
5A biopsy of a flat, blue-gray gingival macule adjacent to a restored lower first molar shows fine, brownish-black foreign granules lining reticulin fibers and the basement membranes of blood vessels and neural sheaths. No significant inflammatory reaction is present. Which of the following is the definitive diagnosis?
A.Mucosal blue nevus of the gingiva
B.Amalgam tattoo (focal argyrosis)
C.Oral mucosal melanoma in situ
D.Lead line of plumbism
Explanation: Amalgam tattoo (focal argyrosis) is an iatrogenic implantation of dental restorative particles. Histopathologically, fine, granular, brownish-black foreign material preferentially coats reticulin fibers of collagen and basement membranes of submucosal vessels, nerves, and muscle fibers, often with minimal or absent foreign body giant cell reaction.
6A 42-year-old heavy cigarette smoker presents with diffuse, brown macular pigmentation of the anterior labial attached gingiva. Biopsy reveals basal layer melanin hyperpigmentation and scattered subepithelial melanophages. Which of the following statements regarding smoker's melanosis is correct?
A.The pigmentation typically shows gradual fading and reversibility over months to years following smoking cessation
B.The lesion carries a 15% to 20% risk of malignant transformation into oral mucosal melanoma
C.The pigmentation is caused by heavy metal deposits from tobacco combustion products coating elastin fibers
D.The hard palate is the most common site of smoker's melanosis in conventional cigarette smokers
Explanation: Smoker's melanosis is a reactive melanocytic response to polycyclic aromatic hydrocarbons in tobacco smoke. It characteristically affects the anterior labial attached gingiva in conventional cigarette smokers (and the hard palate in pipe/reverse smokers). Importantly, the hyperpigmentation is benign, carries no malignant potential, and usually resolves or significantly fades over 1 to 3 years after complete smoking cessation.
7A 52-year-old female presents with an asymptomatic, yellowish-white, sessile, papillary plaque measuring 8 mm on the keratinized attached gingiva. Histopathology demonstrates hyperparakeratinized papillary projections with elongated epithelial rete pegs of uniform depth. The dermal/connective tissue papillae are packed with large, polygonal foamy histiocytes that stain strongly positive for CD68 and negative for S100. What is the diagnosis?
A.Oral squamous papilloma
B.Verruciform xanthoma
C.Verrucous carcinoma
D.Granular cell tumor
Explanation: Verruciform xanthoma is an uncommon, benign mucocutaneous lesion characterized by a papillary or verrucous architecture with lipid-laden, foamy xanthoma cells (foamy histiocytes) strictly confined to the dermal and connective tissue papillae between epithelial rete pegs. These xanthoma cells are reactive histiocytes that express CD68, CD163, and periodic acid-Schiff (PAS) positivity, while testing negative for S100.
8A pedunculated, cauliflower-like, pink-white exophytic growth measuring 5 mm is excised from the soft palate of a 28-year-old patient. Microscopic examination demonstrates multiple finger-like projections lined by stratified squamous epithelium with koilocytic change, supported by delicate fibrovascular connective tissue cores. Which human papillomavirus (HPV) genotypes are most commonly associated with this lesion?
A.HPV 31 and 33
B.HPV 16 and 18
C.HPV 6 and 11
D.HPV 52 and 58
Explanation: Oral squamous papilloma is the most common benign epithelial neoplasm/hyperplasia of the oral cavity and is predominantly associated with low-risk human papillomavirus genotypes HPV 6 and HPV 11. These low-risk viruses induce benign papillary proliferation with superficial koilocytosis without driving genomic instability.
9A 65-year-old male presents with a rapidly growing, dome-shaped nodule with an elevated rolled border and a central keratin-filled crater on the sun-exposed vermilion border of the lower lip that reached 1.5 cm in 4 weeks. Biopsy reveals a cup-shaped architecture with overhanging epithelial lips and mature keratinizing squamous epithelium exhibiting minimal cytologic atypia. Which clinical phase characteristically follows the rapid proliferative phase in this condition?
A.Transformation into diffuse regional lymphadenopathy
B.Rapid hematogenous dissemination to distant viscera
C.Infiltration of underlying cortical bone with osteolysis
D.Spontaneous involution with scar formation
Explanation: Keratoacanthoma (often considered a low-grade, self-limiting variant of squamous cell carcinoma) follows a distinctive triphasic clinical course: rapid growth over 4 to 8 weeks (proliferative phase), stationary maturity phase, and spontaneous regression/involution over 6 to 12 months with expulsion of the keratin plug and residual atrophic scarring.
10Which of the following histopathologic features best distinguishes verrucous carcinoma (Ackerman tumor) of the oral cavity from conventional well-differentiated squamous cell carcinoma?
A.Severe nuclear pleomorphism, atypical multipolar mitotic figures, and loss of p16 expression
B.Deeply infiltrative, ragged jagged cords of atypical squamous cells with vascular invasion
C.Broad, bulbous 'pushing' rete ridges with an intact basement membrane and parakeratin clefting
D.Sheets of primitive spindle-shaped cells with extensive perineural infiltration
Explanation: Verrucous carcinoma is a distinct, low-grade variant of oral squamous cell carcinoma characterized by slow, broad-based exophytic papillary growth with heavily parakeratinized clefts ('parakeratin plugging') and broad, bulbous, blunt epithelial rete ridges that 'push' into the underlying stroma rather than invading as jagged infiltrating cords. Cytologic atypia is strikingly minimal and the basement membrane remains morphologically intact.
