Subcutaneous finger to pigeon egg-sized lumps and nodules

Introduction The clinical manifestations of schizophrenia are the inflammatory mass nodules from the finger to the lower torso of the trunk or lower limbs, the number is 1-2, and the affected part has edema and itching.

Cause

(1) Causes of the disease

Local application of raw frog meat, ingestion of raw or half-baked frog, snake meat or pork, ingestion of live sputum, drinking water or swimming, swallowing into the water of the scorpion containing the original scorpion, and the mites directly enter the skin through the skin wound Tissue causes disease.

(two) pathogenesis

Uncooked frog meat or snake meat is eaten by humans, or water contaminated with scutellaria, which is infected with schistosomiasis, or frog skin infected with mites, directly applied to treat skin ulcers or eye diseases, mites It can cause disease by directly entering the subcutaneous tissue through the skin wound.

Fungal histopathology

The skin lesions are inflammatory mass nodules from the finger to the trunk of the trunk or lower limbs, and the number is 1-2. The affected part has edema and itching. There is no feeling. Parasitic to the eye can cause painful conjunctivitis, or cause eye movement to limit and destroy the eye.

Diagnosis is based primarily on epidemiological history, subcutaneous nodules or mass and biopsy. Anyone who has applied frog meat to wounds, sores, and eyes or has a history of raw frogs, snakes, and pork, and clinical manifestations of subcutaneous nodules and masses should consider this disease. A biopsy can be found in the worm to confirm the diagnosis. The intradermal test of the sputum sputum antigen has an auxiliary diagnostic value.

Differential diagnosis

The subcutaneous nodules are a hard, round or elliptical, painless nodule. The diameter is 0.2 to 10 cm. Often located in more parts of the friction, such as the elbow extension, the Achilles tendon, the scalp, the ischial tuberosity or around the joint. Unusual parts have ears and bridge of the nose. Subcutaneous nodules rarely cause symptoms, occasionally rupture or complicated infection. Typical subcutaneous nodules grow slowly, persist or disappear when the disease is relieved. The appearance of subcutaneous nodules is closely related to high titer serum rheumatoid factor, severe joint destruction and rheumatoid active lesions.

(1) Papular sarcoidosis: damage is a small nodule of needle-to-pea size, also known as miliary-like sarcoidosis. Mainly distributed on the face, neck and shoulders. When the slide is pressed, it shows a pale yellow spot similar to lupus nodules, leaving no trace after disappearing, sometimes leaving pigment spots, atrophy and scars.

(2) Plaque-type sarcoidosis: Hutchinson first reported this unique plaque lesion, a large lobulated nodular plaque with a flat surface and a slightly elevated surface, common in the buccal, nasal and arm.

(3) Psoriasis-like sarcoidosis: plaques with clear boundaries on the trunk and limbs are often present, with psoriasis-like scales on them.

(4) Frostbite-like lupus type: In the parts prone to frostbite, such as ear, pregnancy, cheeks, nose, and toes, symmetry occurs in the shallower red or purple-red plaque. (5) Subcutaneous sarcoidosis is also known as Darier-Roussy sarcoidosis. The solid subcutaneous nodules from the beans to the chestnuts adhere to the skin, and the epidermis is mildly ochre. It is common in the trunk, and the face is rare and has no symptoms.

(6) Scar mesenoma: The damage occurs at the scar site. Such as burns, folliculitis, and scars after herpes zoster. The original scar area is enlarged and the height is increased, which is similar to keloid.

(7) erythrodermic mesothelioma: diffuse distribution of invasive erythema and scaly patches with unclear boundaries.

(8) Nodular erythematous belloid tumor: some patients with sarcoidosis with multiple joint pain with fever, increased erythrocyte sedimentation rate, X-ray examination of hilar lymphadenopathy. Painful subcutaneous nodules occur on the face, back, and extremities. The skin on the surface is red, most common in young women.

(9) mucosal mesothelioma: hard palate, buccal, uvula, and tonsil needles in the mouth, clusters form a flat plaque, small nodules in the conjunctiva and lacrimal glands.

The skin lesions are inflammatory mass nodules from the finger to the trunk of the trunk or lower limbs, and the number is 1-2. The affected part has edema and itching. There is no feeling. Parasitic to the eye can cause painful conjunctivitis, or cause eye movement to limit and destroy the eye.
