Differential diagnosis
Identification of symptoms that are easily confused by sputum proliferation:
Several common diseases: leukoplakia (PVL) is a white spot disease with unknown etiology, chronic proliferative, multiple, and intractable. It is more common in middle-aged and elderly women, and it is common in buccal and sputum. , sputum, tongue, high cancer rate.
Sickle xanthomas: the epidermis is sputum-like or papillary, and the surface keratosis is incomplete. The epidermal nails extend to the dermis and spread in a uniform plane. In the dermal papilla layer, a large number of foam cells are visible, a Sudan black B and scarlet staining. Lipids can be found in the above cells. It can occur in the mouth and genital area, and tuberculous skin tuberculosis is rare, accounting for about 4% to 5%. The incidence was more common in adult males (70.8%). The predilection sites are exposed parts such as hands, feet and hips. Multiple traumatic infections. The rash is characterized by a single dark red papule or a scorpion nodule, which is hard and gradually expands into a sheet, which is papillary-like proliferation and covered with adhesive tendon or shallow ulcer. A smooth, soft, atrophic scar can be seen in the center of the lesion. Histopathology: The epidermis shows verrucous proliferation and dermal tuberculosis granuloma.
Acanthosis nigricans, also known as black keratosis, is a rare skin disease characterized by hyperpigmentation, keratinized skin, papillary or sputum-like proliferation.
It is a benign tumor of the skin caused by abnormal epidermal development. It usually occurs in infants and young children. It is characterized by dense pale brown papules arranged in a linear form of verrucous hyperplasia. The surface of the skin is long and tangible, and it is mostly bulging.
