<b><i>Introduction:</i></b> Lipedematous scalp (LS) is a rare condition characterized by thickened adipose tissue in the subcutaneous layer of the scalp resulting in a soft, spongy, or thick consistency of the scalp. When associated with hair loss, this condition is called lipedematous alopecia (LA). Various imaging modalities have been used to diagnose LS and LA along with histopathology. <b><i>Case Presentation:</i></b> We present 2 cases of LS: a 56-year-old female with a 1-year history of hair thinning, pain, and tenderness at the vertex scalp and a 60-year-old female with a 5-year history of lichen planopilaris presenting with a 1-year history of itching and soreness on the crown of her head. Ultrasound (US) was used for diagnosis, treatment response surveillance, routine clinical examination, and symptom assessment. Follow-up US revealed no improvement in scalp thickness in either case despite symptom improvement and visual improvement in hair growth. <b><i>Discussion/Conclusion:</i></b> US has been reported as a helpful tool in the diagnosis of LS; however, treatment response was better approximated by hair growth and symptom alleviation. We found that once the diagnosis with made with US, clinical monitoring is adequate as symptom improvement and hair growth may not correlate with a change in scalp thickness.

Scalp arteriovenous malformation (AVM) accounts for only 8.1% of all AVM cases. These lesions are made up of an abnormal fistulous tangle of tortuous dysmorphic network of vessels “vascular nidus” directly connecting between the feeding arteries and draining veins, without capillary connection, located within the incision subcutaneous layer. With time, these congenital lesions may evolve and enlarge and clinically manifest with variable features. The only effective method of preventing evolution of these malformations is to exclude the lesion completely from the circulation. Involvement of the orbit and face may cause severe facial disfigurement, proptosis, visual obstruction and even facial palsy. These lesions may be complicated by ulceration, infection and profuse bleeding. We present a rare case of 40-year-old female with a recurrent congenital scalp-orbital AVM causing proptosis, visual obstruction on the right eye with severe facial disfigurement. The lesion was successfully excised with acceptable cosmesis and removal of the visual obstruction. A brief literature review, imaging findings and the surgical techniques have been presented.

Abstract The purpose of current work is to study the effect of carbon dioxide on the shrinkage of smoked fish and to develop a technical solution for the implementation of technology with the use of CO2 in fish trade. We use mackerel, flounder and crucian carp as test samples. The studies were carried out in two versions: storage of fish in a chamber under traditional conditions and with the addition of carbon dioxide (CO2) to the refrigerating chamber. The use of carbon dioxide gas during the storage of smoked fish leads to an increase in the water-holding capacity of the fish in comparison with the traditional storage method. In our proposed method of storage in a cold atmosphere with CO2, fish shrinkage is reduced. The carbonate ions well bind water molecules in the hydration shell due to positive hydration, which slows down the processes of hydrolysis and oxidation of lipids inside the subcutaneous layer and preserves the moisture-retaining capacity of tissues. Thus, the use of carbon dioxide in the storage of smoked fish reduces weight loss and does not affect the appearance of the fish.

Pilomatricoma(or calcifying epithelioma) is a not common benign solitary tumor originated from outer root sheath cell of hair follicle or hair follicle of sebaceous glands. The tumor usually presents as an asymptomatic, hard, superficial located, and skin colored to reddish blue cutaneous mass. Most of the tumors are less than 10mm in diameter and adherent to the skin. Recently, 48-year-old man presented with cheek mass. The tumor was 2.6cm sized and located at the subcutaneous layer of cheek on CT scan. The tumor was clearly removed via transoral approach with buccal incision leaving no wound on face. The mass was confirmed as pilomatricoma on pathologic examination. Herein, we report our experience with literature review.

Lipoma in birds is a benign tumor of adipose cells that often occurs in the subcutaneous area. White-rumped shama, more than three years old, was rushed to the puskesmas with symptoms of decreased activity and singing ability. The results of the examination were two round, multi-focal masses, firmly demarcated, yellowish in color with a soft, chewy consistency measuring ± 4 x 2 x 1 cm on the chest and ± 1 x 1 x 1 cm. in the abdominal area, firmly attached to the subcutaneous layer since six months ago, and getting bigger. The feathers around the mass are shed and vascularized on the surface of the mass. Surgery was performed because the mass suspected of being a tumor growing rapidly and causing pain. It was fasted two hours before surgery and the anesthetic used was a combination of ketamine HCl and xylazine. Postoperative therapy using the antibiotic enrofloxacin, ketoprofen analgesics, 0.9% NaCl fluid therapy and topical antibiotic gentamicin ointment. The tumor that has been successfully removed is yellowish in color with several areas of hyperemia and an oily surface. The results of histopathological examination characterized by the presence of adipose cells that appeared to proliferate well confirmed that the tumor was a lipoma.

The face conveys our conscious and subconscious emotions and projects vulnerability in disfigurement. Functionally, the face encompasses the muscles that surround our eyes, nose and mouth, contributing to the sphincters and dilators that allow the fine motor control of our eyelids, nostrils and lips, respectively. The face forms the anterior part of the head medial to the ears and between the hairline superiorly and the chin inferiorly. It comprises everything that lies between what is visible anteriorly and laterally. The face consists of four recognisable tissue planes – skin, a subcutaneous layer of fibroadipose tissue (held responsible for some of the changes of the ageing face), the superficial muscular aponeurotic system and the parotidomasseteric fascia. The scalp forms the soft tissue envelope of the cranial vault. The triad it forms with the forehead anteriorly and the temporal regions laterally should be considered as a continuum rather than three separate entities.

<p class="abstract">Subcutaneous fungal infections are caused by penetration of the causative fungi into the subcutaneous layer and usually present as single, localised non-tender nodular swelling. The diagnostic process is a vital dynamic process that requires effective communication and efficient collaboration. Aspergillus hyphae invade host tissues through release of various toxins like proteases, phospholipases, hemolysins, gliotoxin, aflatoxin, phthioic acid and other toxins. Under general anesthesia and proper aseptic conditions using Moure incision surgical debulking of the pre-maxillary mass was done and post-operatively oral antifungal medication was started. Multiple cystic swelling was sent for histopathological examination and found to be non-invasive Aspergillus fungal infection. Subcutaneous form of aspergillosis manifest as subcutaneous fungal infection. We presented an unusual case report of 45 years old immunocompetent female with cystic presentation of aspergillosis involving premaxillary region.</p>

Necrotizing fasciitis with secondary necrosis of the subcutaneous tissues is a rapidly progressive inflammatory infection of the fascia. The propagation velocity is directly proportional to the thickness of the subcutaneous layer. Necrotizing fasciitis travels around the plane of the fascia. These are primarily two types, i.e., respectively, mono microbial and poly microbial infections. The most common comorbidity associated with necrotizing fasciitis is diabetes mellitus. Up to 44.5 percent of patients with this disorder are diabetic. Diabetes patients normally have a type I poly microbial disease. Diabetic patients who, due to poor immunity, are more vulnerable to such an infection. Diabetic patients show delayed healing of cutaneous wounds and increased susceptibility to infection.
