histologic, and EMG criteria).
3. No histologic abnormalities other than degeneration and regeneration of muscle fibers + reaction to those changes (infiltration by fat and connective tissue); no abnormal storage of metabolic products.
4. All symptoms are effects of striated muscle weakness (heart and visceral muscles may also be involved).
5. Weakness becomes progressively worse (
Histologically, the islets consist of three major and at least two minor cell types.
Beta cells, which synthesize and secrete insulin, make up about 60% of a typical islet.
Alpha cells are the source of glucagon, 30% of islet tissue.
Delta cell, which are less abundant, produce somatostatin.
F cells, which secrete pancreatic polypeptide.
Fifth cell type that secretes ghrelin.
Fifty cell typ
Histologically there is a consistent infiltration with dissociation of the surrounding muscle fiber. Infiltrating lipoma can be excised with surrounding normal muscle and tissue to avoid recurrence.
This case is a 57-year-old female with a painless swelling of the right cervical and parotid areas diagnosed as large infiltrating lipoma by clinical examination and radiographic findings. The pati
확실하지 않지만, 손가락 끝 혈관확장을 일으키는 체액(humoral)의 물질에 의한 이차성 변화로 보인다. the condition may result from megakaryocytes and platelet clumps that have escaped filtration in the pulmonary bed and have entered the systemic circulation. Platelets then may release platelet-derived growth factor at the nail bed, causing periosteal changes
